+		    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) 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., 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) 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.

+to 0.47: (all changes by Thomas Flynn)
+- Added ifdefs to .h files to allow multiple inclusion
+
+- Moved a bunch of functions from gltron.c to engine.c
+  These seem to be functions necessary for the game and do not contain OpenGL

+	setCol();
+	clearCol();
+	getCol();
+	turn();
+	initDisplay();
+	changeDisplay();
+	initGame();
+	initdata();
+	colldetect();
+	doTrail();
+	fixTrails();
+	clearTrails();
+	mainIdle();
+	gameIdle();

+- Added argument to drawTraces() so that pfTron knows which player (0,1,2,3)
+  to draw traces for.
+
+- Created getElapsedTime() to replace frequent calls to 
+  glutGet(GLUT_ELAPSED_TIME); which are specific to glut.
+
+- Changed name of Display structure to gDisplay.  Conflicts with Display 
+  structure in Xlib.h
+
+- Changed movePlayers() to call setGameIdleFunc() where it used to call 
+  glutIdleFunc().  Needed to move that glut call elsewhere.
+
+- Changed it so that scores are not updated if in screensaver mode.
+  Didn't seem to make sense.  If you disagree, lemme know.
+
+- Changed it so that the sound file is searched for in $GLTRON_SNDDIR then ./
+  then /usr/share/games/gltron.
+
+- Decided to get consistant with the naming.  All instances of gltron are now
+  gltron.
+
+- Added gltron.rpm.spec and gltron_sound.rpm.spec.
+
+- New Makefile.  New rules: install, packages.  Must be root for both.
+  The packages rule makes .rpms, .tgz, and .deb files.
+
+to 0.46:
+- fixed bug with -k option, no more crashes
+- capped FPS at 90-100 FPS (you need more???)
+- fixed crazy FPS counter under windows - now shows the real numbers
+- fixed alternate camera mode under windows
+- did a new windows version (with sound!)
+- included glut.dll in the win32 distribution
+- changed texture format, it's now char[] instead of char*, that should
+remove problems with non-gcc compilers
+- fullscreen rendering under win32 (switched to glutGameMode where avaiable)
+- added '-i' switch, forces in-a-window-rendering under win32
+- added '-v' switch, demo/screensafer mode (don't use with -f!)
+to 0.45:
+- added sound (Song by Peter Hajba)
+- added load/save for preferences
+- split code over several files
+
+to 0.44: 
+- added help screen
+
+to 0.43:
+- fixed bug with uninitialised variable 'loop' in mainIdle() that
+  caused the game to crash sometimes
+- added #ifdefs for FreeBSD (patch from Andrey Zahkhatov)
+ 
+to 0.42:
+
+- added glow around players (patch from Xavier Bouchoux)
+- added second camera (patch from Mike Field)
+- added nice color fade to model color where actually the bikes should be
+  (I hope I'll receive the models soon)
+- added optional erasing of crashed players (like in the movie)
+- added optional fast finishing of the game after human crashes (no more
+  long wait for next round if the computers decide to go in circles around
+  the block)
+- added message who actually won the round (if you can't find it, it's
+  at the bottom of the screen)
+- added CREDITS file
+- added keys for steering player 3 & 4 (you're silly if you think you
+  can get 4 people to use one keyboard)
+- fixed a few minor bugs (e.g. speed change is now persistent)
+- changed behaviour of Display->onScreen
+- added keys for cycling players in upper/lower window in split-screen mode
+- changed FOV to 105
+- added keys to change FOV
+- introduced a bug that makes the game freeze (very very rare), perhaps
+  someone finds out why?
+
+to 0.41:
+
+- changed floor & wall textures (I'm still no artist though) 
+- changed trail colors to fit new floor texture
+- multiple perspectives, view 1, 2 or 4 players (F1-F3 changes
+  that on the fly) - it's worth the download!
+- fixed typos with -h switch
+- fixed Makefile, compiles now with -O2 instead of -g (debug)
+  I can't see an obvious speed increase though
+- added this CHANGELOG file

+GLtron - Installation from source
+
+If you install from CVS, read also README.CVS
+
+Requirements:
+
+Get a working OpenGL / Mesa installation
+Get libpng / zlib (standard on almost any system)
+Get SDL-1.2 (1.1 might work, but is unsupported)
+
+If you want sound, you need to grab SDL_sound 0.1.4 or later from
+http://icculus.org/SDL_sound/
+
+Required libraries for SDL_sound: libmikmod 3.1.5 or newer
+
+Compiling:
+
+./configure
+make
+
+And (probably as root)
+make install
+
+Data files get installed by default to /usr/local/share/gltron
+The config file gets stored in $HOME/.gltronrc and any screenshots you
+make get stored in $HOME/gltron-$version-$index.png
+
+You can tweak most file locations using ./configure options.
+Try ./configure --help
+
+If you want to play from the source directory, use
+./configure --enable-localdata
+
+GLtron will then chdir() to the binary location upon startup, and
+load things from there. This is useful for the loki installer.
+You can put everything (binary & data) into one directory, and but
+a symlink into e.g. /usr/local/bin.
+
+Usage:
+
+'gltron -h' lists a few runtime options. Most notably is the -O option,
+which will speed things up greatly *if you don't have a 3D card*. Don't
+use this unless the game runs really slow, the visuals will suffer terribly.
+
+Start gltron with the -s option if you don't want the sound playing.
+
+Visit http://www.gltron.org/ frequently for updates and patches!

+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+This is Lua 4.0.
+See HISTORY for a summary of changes since the last version.
+
+* What is Lua?
+  ------------
+  Lua is a powerful, light-weight programming language designed for extending
+  applications. Lua is also frequently used as a general-purpose, stand-alone
+  language.
+
+  Lua combines simple procedural syntax (similar to Pascal) with powerful
+  data description constructs based on associative arrays and extensible
+  semantics. Lua is dynamically typed, interpreted from bytecodes, and has
+  automatic memory management, making it ideal for configuration, scripting,
+  and rapid prototyping.
+
+  Lua is a language engine that you can embed into your application.
+  This means that, besides syntax and semantics, Lua has an API that
+  allows the application to exchange data with Lua programs and also to
+  extend Lua with C functions. In this sense, Lua can be regarded as a
+  language framework for building domain-specific languages.
+
+  Lua is implemented as a small library of C functions, written in ANSI C,
+  and compiles unmodified in all known platforms. The implementation goals
+  are simplicity, efficiency, portability, and low embedding cost.
+  The result is a fast language engine with small footprint, making it
+  ideal in embedded systems too.
+
+  Lua was awarded the first prize (technological category) in the
+  Second Compaq Award for Research and Development in Computer Science in 1997.
+  This award was a joint venture of Compaq Computer in Brazil, the Brazilian
+  Ministry of Science and Technology, and the Brazilian Academy of Sciences.
+
+  Lua has been used in many different projects around the world.
+  For a short list, see http://www.tecgraf.puc-rio.br/lua/uses.html .
+
+* Availability
+  ------------
+  Lua is freely available for both academic and commercial purposes and
+  can be downloaded from the sites below. See COPYRIGHT for details.

+This is the standard Lua library.
+It is implemented entirely on top of the official Lua API as declared in lua.h,
+using lauxlib.c, which contains several useful functions for writing libraries. 
+We encourage developers to use lauxlib.c in their own libraries.
+The code of the standard library can be read as an example of how to export
+C functions to Lua.

+  We assume that instructions are unsigned numbers.
+  All instructions have an opcode in the first 6 bits. Moreover,
+  an instruction can have 0, 1, or 2 arguments. Instructions can
+  have the following types:
+  type 0: no arguments
+  type 1: 1 unsigned argument in the higher bits (called `U')
+  type 2: 1 signed argument in the higher bits          (`S')
+  type 3: 1st unsigned argument in the higher bits      (`A')
+          2nd unsigned argument in the middle bits      (`B')
+
+  A signed argument is represented in excess K; that is, the number
+  value is the unsigned value minus K. K is exactly the maximum value
+  for that argument (so that -max is represented by 0, and +max is
+  represented by 2*max), which is half the maximum for the corresponding
+  unsigned argument.
+
+  The size of each argument is defined in `llimits.h'. The usual is an
+  instruction with 32 bits, U arguments with 26 bits (32-6), B arguments
+  with 9 bits, and A arguments with 17 bits (32-6-9). For small
+  installations, the instruction size can be 16, so U has 10 bits,
+  and A and B have 5 bits each.
