Added slim-fork to the repo

Browse source 
- This introduces a minimalist display manager for the suckless-utils suite
- Added crudely written scripts for reloaading slim's theme via pywal,
  meaning no on-the-fly reloading using keybinds as nost people wouldn't
have their sudo passwordless
- This is based on slim-fork 1.4.0 version.

## Notes
### slim notes
To reload the preset theme (located in `/usr/share/themes/slim/suckless`), then run `.cache/wal/slim-reload` **after** running pywal. The script must also be ran as sudo.
This is, if you wanted a display manager added. The scripts also works a workaround unless if slim could handle loading themes from other dirs.
### eww notes
The weather widget is pretty barebones as of now. Report bugs if found.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

1.4.0 - 2023.01.21
* - BREAKING CONFIG CHANGE - the position of the passwd_feedback in slim
is now relative to the screen, not the panel. This is now consistent
with slimlock and with the session and other messages.
* The selected session is now preserved over failed logins
* When testing themes with the -p option, the size of the window can now
be specified, and the theme is previewed correctly for that size.
* On exit from theme test, the "test message" now reports user and session
* Failed login feedback is now disabled by default or if position negative
* Applied some Devuan patches
- Set the XDG_SESSION_CLASS. This fixes Gentoo bug #727544 - failure to
register sessions with elogind in some instances. The (incorrect) bug
note in the man page has therefore been removed again.
- Use $DISPLAY instead of hardcoding :0.0 in sessionstart/stop commands
- No longer always builds slimlock if using PAM - it must be explicitly
enabled
- Fixed formatting in slimlock man page
- A couple of typos fixed in strings
* Updated the README and encoded in UTF-8
* Corrected the handling of the -n / -nodaemon option so that it doesn't
swallow the next option if given as -n
* Bug fixes in slimlock
- The active entry is for password, so show the password prompt, not the
username one
- Don't react to F1, as it isn't appropriate and used to blank the
screen
- Keep it all on one screen even when the WM hasn't set a "primary" for
RandR purposes
* Fix ticket #4 - the config parser now works properly. Previously it got
confused by option names that were substrings of other option names
* Themes with "background_style color" no longer need a redundant image
file to make them work.
- This needed a bit of a re-write of the image handling, which also
improves efficiency
* New default theme - the old one is retained as "original"
* Some general documentation improvements (man pages, comments in example
files)
1.3.9 - 2022.11.18
* Changed the handling of the "auth failed" message in DM mode so that it
remains on display until a key is pressed.
* Added a command line option to specify the configuration file
* Allow the logfile to be specified as "stderr" to write to stderr
Also now writes all log messages to stderr if they are printed before
the log file is open, including when using the -p option.
* Added a configuration option to retain the user name if authentication
fails (which is probably more helpful if you just mistype your password)
* Applied a modified version of the "wait for the X server" patch from guix
* No longer unnecessarily re-opens an already open X display interface.
Similarly removed a redundant "get root window" call
* Deleted some unused member variables and methods. Various other internal
clean-up
* Reverted the install location definition for the configuration file, as
the CMAKE_INSTALL_SYSCONFDIR wasn't right
* Added a "bug" note to the man page, for the reliance on sessreg, which
causes occasional misbehaviour for some people.
1.3.8 - 2022.03.01
* Fixed some bugs listed on bugs.gentoo.org:
832303 - failed to build with clang, Invalid suffix on string literal
580458 - open fd on /var/log/slim.log passed to session
* Fixed handling of log stream so that all the code uses the same instance
* Handle return values from calls, to clean up warn-unused-result warnings
* Fixed "sessions" config option (the earlier patch was incomplete)
* Several QA improvements
* Updated cmake config - use standard install paths, don't force options
1.3.7 - 2022.01.30
* Imported several bug fixes from the Gentoo package:
libslim-cmake-fixes
disable-ck-for-systemd
reinstate sessions config option as an alternative to sessiondir
systemd session compatibility
remove zlib dependency
envcpy-bad-pointer-arithmetic patch
add-missing-libgen_h
wrong comparison for XCreateGC error return (GCC11 needs it fixed!)
* Fixed a bug in handling expired user accounts with PAM
* Show a message on login failure (using the same method as slimlock)
--- The releases below were the original SLiM project ---
1.3.6 - 2013.10.01
* Merge slimlock.
* Add support ^H (like backspace).
* And fix some bugs.

* And fix some bugs.
1.3.4 - 2012.06.26
* Replaced stderr writes function.
* Fix numlock control.
* Fix build with GLUT.
* Fix PAM authentication.
1.3.3 - 2012.02.22
* Change build system to CMake.
* Add support ConsoleKit.
* Fix some bugs....
1.3.2 - 2010.07.08
* Add support xauth secret.
* Add xnest_debug mode.
1.3.1 - 2008.09.26
* Added focus_password config option for focusing password
automatically when default_user is enabled
* Added auto_login option
* Fixed uninitialized daemonmode, see
http://www.freebsd.org/cgi/query-pr.cgi?pr=114366
* Fixed maximum length for password
* Introduced customization options for session text:
font, colors, position, shadows.
1.3.0 - 2006.07.14
* Added PAM support by Martin Parm
* Fixed segfault on exit when testing themes. Thanks
to Darren Salt & Mike Massonnet
* Fixed vt argument detection, thanks to Henrik Brix Andersen
* Corrected reference to input_color in the default theme
* Fixed default shell setting
* Fix segfault when calling XCloseDisplay(NULL); thanks Uli Schlachter
1.2.6 - 2006.09.15
* Bug #008167: Update pid when in daemon mode
* Fixed warnings when compiling with -Wall. Thanks to
KIMURA Masaru
* Fixed major memory leaks with repeated login (bug #007535)
1.2.5 - 2006.07.24
* hiding of the cursor is now an option (disabled
by default) since some WMs does not re-initialize
the root window cursor.
* The X server is restarted when the user logs out.
This fixes potential security issues with user-launched
apps staying attached to the root window after logout.
* Bug #7432 : Added proper Xauth authentication: the X server
is started with the -auth option and the user who logs
in has his .Xauthority file initializated.
1.2.4 - 2006.01.18
* Added commands for session start and stop
(i.e. for session registering)
* Added automatic numlock on/off option
* Support for numpad Enter key

* Added FreeBSD, NetBSD, OpenBSD support
* Replaced autotools with plain makefile(s)
* Added 'suspend' command (untested, we don't use it)
* Added support for %theme variable in login command
1.2.2 - 2005.05.21
* fix panel drawing on screens <= 1024x768
* Don't start X server unless valid theme found
* revert to 'default' of invalid theme specified
* try all themes from a set if one doesn't work
1.2.1 - 2005.05.17
* draw input directly on panel
1.2.0 - 2005.05.16
* added theme preview (slim -p /path/to/theme)
* added JPEG support for panel image
* added 'center' background type and 'background_color' option

* Fix login failure when no shell specified in /etc/passwd
* Print error when login command execution fails
* add XNEST_DEBUG ifdef's to allow for easy debugging
* Add support for Ctrl-u and Ctrl-w
* Add 'vt07' to server arguments if not already specified
* Removes daemon option from the config file. Use slim -d

README file for SLiM
Rob Pearce <slim@flitspace.org.uk>
INTRODUCTION
SLiM (Simple Login Manager) is a graphical login manager for X11.
It aims to be simple, fast and independent from the various
desktop environments.
SLiM was originally based on the last stable release of Login.app
by Per Lidén.
Features:
- External themes and configuration
- PNG support with alpha transparency for panel
- PNG / JPEG support for backgrounds
- XFT / freetype support
- Double or single (GDM-style) inputbox support
- PAM support for authentication
- Compatible with ConsoleKit or logind, OpenRC or systemd, etc.
- CMake build procedure
INSTALLATION
see the INSTALL file
USAGE
SLiM is intended to be run automatically as part of the system
startup. Get your SysVInint, OpenRC or systemd to run the slim
executable, with the -d option if you want it to run as a daemon
in the background (recommended for OpenRC, systemd may work
better without)
As you would expect of a login manager, you enter your username
and password to login. By default, the ~/.xinitrc file is run,
so be sure to have a working .xinitrc file in your home. This
behaviour is configurable, and may be set up differently by the
distro package.
Special usernames can be entered to run commands that are
configurable in the config file:
- console: start a console login
- exit: exit SLiM (this may not have desirable results)
- halt: shut down the system
- reboot: reboot the system
Pressing the F11 key executes a user-specified command (see the
configuration file). The default is to take a screenshot, if the
'import' program is available.
CONFIGURATION
/etc/slim.conf is the main configuration file. Alternative files
can be specified on the command line.
Options are explained in the file itself
THEMES
The appearance (and some parts of the behaviour) of SLiM depends
on the "theme" specified by the configuration file. See the file
THEMES for details.

Quick THEME howto for SLiM
Some basic information regarding the slim theme format.
Read this file if you plan to make some theme for
the program, and of course have a look at the included themes
GENERAL CONCEPT
A SLiM theme essentially consists of:
- a background image (background.png or background.jpg)
- a panel image (panel.png or panel.jpg)
- input box(es) and messages and their placement
and properties (slim.theme)
The panel and background images can be a PNG or JPEG file.
The panel is blended into the background image,
taking care of alpha transparency.
SUPPORTED FORMATS
- fonts: use the xft font specs, ie: Verdana:size=16:bold
- colors: use html hex format, ie #0066CC
- positions: can be either absolute in pixels, ie 350
or relative to the container, ie 50% is in the middle
of the screen.
OPTIONS
The following is an example slim.theme file
----------------------------------------------------------------------
# Color, font, position for the messages (ie: shutting down)
msg_color #FFFFFF
msg_font Verdana:size=16:bold
msg_x 50%
msg_y 30
# Color, font, position for the session list
session_color #FFFFFF
session_font Verdana:size=16:bold
session_x 50%
session_y 90%
# style of background ('stretch', 'tile', 'center') and color
background_style stretch
background_color #FF0033
# Horizonatal and vertical position for the panel.
input_panel_x 50%
input_panel_y 40%
# Input controls horizontal and vertical positions relative to
# the panel.
# Set input_pass_x and input_pass_y to -1 to use a single input
# box for username/password (GDM Style).
# Note that these fields only accept absolute values.
input_name_x 40
input_name_y 100
input_pass_x 40
input_pass_y 120
# Input controls font and color
input_font Verdana:size=12
input_color #000000
# Welcome message position. (relative to the panel)
# use -1 for both values or comment the options to disable
# the welcome message
welcome_x 50%
welcome_y 38
# Font and color for the welcome message
welcome_font Verdana:size=16:bold:slant=italic
welcome_color #d7dde8
# 'Enter username' font and foreground/background color
username_font Verdana:size=12
username_color #d7dde8
# 'Enter username' and 'Enter password' position (relative to the panel)
# use -1 for both values to disable the message
# note that in case of single inputbox the password values are ignored.
username_x 50%
username_y 146
password_x 50%
password_y 146
# The message to be displayed. Leave blank if no message
# is needed (ie, when already present in the panel image)
username_msg Please enter your username
password_msg Please enter your password
# Optional message to show on a failed login. Similar set of values
# to the above. Use -1 for the x & y to disable (default).
password_feedback_x 50%
password_feedback_y 165
password_feedback_msg Authentication failed
# The font and color are inherited from msg_xxx
----------------------------------------------------------------------
SHADOWS
The 'msg', 'input', 'welcome', 'session' and 'username' sections
support shadows; three values can be configured:
- color: the shadow color
- x offset: the offset in x direction, relative to the normal text
- y offset: the offset in y direction, relative to the normal text
So to add a text shadow to the welcome message, add the following
to slim.conf:
----------------------------------------------------------------------
welcome_shadow_xoffset -2
welcome_shadow_yoffset 2
welcome_shadow_color #ff0000
----------------------------------------------------------------------
The other keys are analogous:
----------------------------------------------------------------------
# for username and password label
username_shadow_xoffset 2
username_shadow_yoffset -2
username_shadow_color #ff0000
# for the input fields
input_shadow_xoffset 1
input_shadow_yoffset 1
input_shadow_color #0000ff
# for the messages:
msg_shadow_xoffset 1
msg_shadow_yoffset 1
msg_shadow_color #ff00ff
# For the session:
session_shadow_xoffset 1
session_shadow_yoffset 1
session_shadow_color #ff00ff
----------------------------------------------------------------------

Important things
----------------
- Make it work better with multi-screen setups
Improvements suggested long ago
-------------------------------
- Don't start X server if theme's not found
- i18n
- FreeBSD fixes
- restart X server on ctrl-alt-backspace
Other thoughts for improvement
------------------------------
- position text to fit screen, e.g. when at 90% position
- allow nested config
- make slimlock handle themes the same as slim
- option to run X server as non-root

.SH NAME
\fBslim \fP- Simple LogIn Manager
\fB
.SH SYNOPSIS
.nf
.fam C
\fBslim\fP [\fIoptions\fP] [<arguments>]
.fam T
.fi
.SH DESCRIPTION
SLiM is a lightweight login manager for X11, allowing the initialization
of a graphical session by entering username and password in a login screen.
It is desktop-agnostic and should work (suitably configured) with any
session style.
.SH OPTIONS
.TP
.B
\fB-c\fP /path/to/config
select a non-standard configuration file instead of /etc/slim.conf
.TP
.B
\fB-d\fP
run as a daemon
.TP
.B
\fB-n\fP
do NOT run as a daemon
.TP
.B
\fB-s\fP
be systemd compatible by disabling consolekit support. This option does
nothing if consolekit support has not been built in.
.TP
.B
\fB-p\fP /path/to/theme
display a preview of the theme. An already running X11 session
is required for theme preview.
.TP
.B
\fB-w\fP <www>x<hhh>
set the size of the window used for theme preview. This option is only valid
after a -p option
.TP
.B
\fB-h\fP
display a brief help message
.TP
.B
\fB-v\fP
display version information
.SH EXAMPLES
.TP
.B
\fBslim\fP \fB-d\fP
run \fBslim\fP in daemon mode
.TP
.B
\fBslim\fP \fB-p\fP /usr/share/slim/themes/default \fB-w\fP 800x600
preview of the default theme at low resolution
.SH STARTING SLIM AT BOOT
Please refer to the documentation of your Operating System to make \fBslim\fP
automatically startup after the system boots. In particular, the method is
very different between SysV, OpenRC, runit and systemd init processes.
.SH CONFIGURATION
Global configuration is stored in the /etc/slim.conf file. See the comments
inside the file for a detailed explanation of the \fIoptions\fP.
.SH USAGE AND SPECIAL USERNAMES
When started, \fBslim\fP will show a login panel; enter the username and
password of the user you want to login as.
.PP
Special usernames:
.TP
.B
console
open an xterm login console. No password needed
.TP
.B
exit
quit \fBslim\fP. No password needed. See the note in \fBBUGS\fI.
.TP
.B
halt
shutdown the machine
.TP
.B
reboot
reboot the machine
.TP
.B
suspend
power-suspend the machine
.PP
See the configuration file for customizing the above commands.
The 'halt' and 'reboot' commands need the root password, and hence may not
work on systems where root login is disabled.
.PP
Shortcuts:
.TP
.B
F11
executes a custom command (by default takes a screenshot)
.TP
.B
F1
choose session type from session list.
.SH BUGS
When run as a daemon from OpenRC (and possibly other init systems), causing
SLiM to quit can sometimes result in a blank screen and unresponsive computer.
This includes when using the "exit" special username.
.PP
Probably still a few more but I'm working on them.

.SH NAME
\fBslimlock\fP - Unholy Screen Locker
\fB
.SH SYNOPSIS
.nf
.fam C
\fBslimlock\fP [\-v]
.fam T
.fi
.SH DESCRIPTION
The Frankenstein's monster of screen lockers. Grafting SLiM and slock together
leads to blood, tears, and locked screens.
.SH OPTIONS
.TP
.B
\fB-v\fP
display version information
.SH CONFIGURATION
Slimlock reads the same configuration files you use for SLiM. It looks in
\fICFGDIR/slim.conf\fP and \fICFGDIR/slimlock.conf\fP, where \fICFGDIR\fP
is defined when built - usually \fI/etc\fP.
The options that are read from slim.conf are
hidecursor, current_theme, background_color and background_style,
screenshot_cmd, and welcome_msg. See the SLiM docs for more information.
slimlock.conf contains the following settings:
.TP
.B dpms_standby_timeout
number of seconds of inactivity before the screen blanks.
.BI "Default: " 60
.TP
.B dpms_off_timeout
number of seconds of inactivity before the screen is turned off.
.BI "Default: " 600
.TP
.B wrong_passwd_timeout
delay in seconds after an incorrect password is entered.
.BI "Default: " 2
.TP
.B passwd_feedback_msg
message to display after a failed authentication attempt.
.BI "Default: " "Authentication failed"
.TP
.B passwd_feedback_capslock
message to display after a failed authentication attempt if the CapsLock is on.
.BI "Default: " "Authentication failed (CapsLock is on)"
.TP
.B show_username
1 to show username on themes with single input field; 0 to disable.
.BI "Default: " 1
.TP
.B show_welcome_msg
1 to show SLiM's welcome message; 0 to disable.
.BI "Default: " 0
.TP
.B tty_lock
1 to disallow virtual terminals switching; 0 to allow.
.BI "Default: " 1
.TP
.B bell
1 to enable the bell on authentication failure; 0 to disable.
.BI "Default: " 1
.SH BUGS
Where the theme defines a welcome message or password prompt, \fBslimlock\fP
displays them in the wrong place.
.PP
Using the same theme as \fBslim\fP assumes the theme is appropriate. Most of
the themes out there (including our defaults) put the word "Login" on the
panel, which isn't quite right for a screen lock.
.PP
To alleviate both of these, you can specify a different theme in
\fICFGDIR/slimlock.conf\fP, which will override the setting in
\fICFGDIR/slim.conf\fP, but you still need to find (or create) a suitable
lock theme.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.
