X
X% General Comments
X% ----------------
X% This set of TeX definitions exists for two reasons:
X%
X%    1. To shorten and neaten the FunnelWeb TeX output.
X%    2. To allow users to fiddle with the output format in their input files
X%       (by inserting redefining "\def"s) without having to resort to
X%       modifying the FunnelWeb code.
X%
X% The user is warned that these definitions may be changed from time to time
X% (but probably not much). The user should not be too sneaky. In particular,
X% users wishing to redefine some of these macros should do so in an explicitly
X% defined section at the top of their input file. This will mean that in the
X% event of problems, that section can simply be deleted or commented out to
X% allow the document to at least be typeset in the default format. Users should
X% limit themselves to redefining these macros in such a section and should
X% refrain from using the macros throughout their documents.
X
X
X% Environment Parameters
X% ----------------------
X% \tolerance tells TeX how tolerant it should be about making bad line and
X% page breaks. Here we set it to it's maximum, as
X%   1) Computer programs are likely to cause lots of bad breaks.
X%   2) In most cases the user would probably rather get the TeX file through
X%      TeX without any errors than fiddle with spacings for perfection.
X\tolerance=10000
X
X% I don't like indentation as it makes the page look more busy. Instead,
X% paragraphs are separated by a little space (see next).
X\parindent=0pt
X
X% In many cases, users will produce documents with long runs of paragraphs.
X% In order to space out these paragraphs, it is convenient to maintain a
X% prevailing non-zero \parskip (end-of-paragaph skip). The only trouble is
X% that the skip becomes a problem in macro definitions which require no skip
X% and so we have to turn the skip on and off. The following two macros
X% simplify this process.
X\def\fwparskipon{\parskip=\medskipamount}
X\def\fwparskipoff{\parskip=0pt}
X\fwparskipon
X
X% Setting raggedbottom allows TeX to leave a bit of space at the bottom of the
X% page in order to better vertically align the rest of the page (e.g. skips
X% won't stretch as much). It also means that headings are less likely to be
X% isolated at the bottom of the page without any following text.
X\raggedbottom
X
X
X% Fonts
X% -----
X% Most of the typeset output is set in 10pt roman and 10pt tt font.
X% The major extra font needs spring from titles and headings.
X% For portability's sake we use only the following fonts:
X%    cmr10
X%    cmbx10
X%    cmtt10
X% and some enlargements of them. These fonts are all "standard" fonts
X% in Plain TeX. See The TeXbook p.350.
X\font\fwfontnote=cmr7
X
X\font\fwfontnorm=cmr10
X\font\fwfontnorma=cmr10 scaled \magstep1

X% Macros for Stylistic Details
X% ----------------------------
X% This section contains all the fiddly little macros for setting the details
X% of each macro definition.
X
X% Macro definitions are sandwiched by calls to these macros which can be used
X% to sort out the spacing before and after the macro definition.
X\def\fwbeginmacro{\fwparskipoff\bigskip}
X\def\fwendmacro{\fwparskipon\par}
X
X% These macros deal with the macro name and definition line.
X\def\fwmacroname#1#2{{\sl #1\/}$\lbrack$#2$\rbrack$}
X\def\fwfilename#1#2{{\bf #1}$\lbrack$#2$\rbrack$}
X\def\fwzero#1{{\bf Z}}
X\def\fwmany#1{{\bf M}}
X\def\fwequals{ $\equiv$}
X\def\fwplusequals{ $+\equiv$}
X
X% Now for the actual body of the definition. It looks nice to have the tt
X% code indented a little. Again, we use macros instead of writing direct TeX,
X% so as to allow the user to fiddle this stuff to taste without having to
X% modify the FunnelWeb C code.
X\def\fwodef{\parindent=15pt\vskip0pt$\lbrace$\parindent=20pt}
X\def\fwcdef{$\rbrace$\vskip0pt\parindent=0pt}
X\def\fwoquote{`}
X\def\fwcquote{'}
X\def\fwoparen{$($}
X\def\fwcomma{$,$}
X\def\fwcparen{$)$}
X\def\fwparam#1{$\diamond #1$}
X\def\fwparams#1{$(\diamond #1)$}
X
X% These macros deal with the notes that are appended at the end of each
X% macro definition. Note that even though \fwisafile,\fwusedin, and \fwseealso
X% have the same definition, they are given different names so as to allow the
X% user to redefine these macros to typeset each kind of information differently
X% if desired.
X\def\fwbeginmacronotes{\begingroup\baselineskip=9pt\smallskip}
X\def\fwnote#1{{\fwfontnote #1}\par}
X\def\fwisafile#1{\fwnote{#1}}
X\def\fwusedin#1{\fwnote{#1}}
X\def\fwseealso#1{\fwnote{#1}}
X\def\fwendmacronotes{\endgroup}
X
X
X% Macros to Typeset Program Code Verbatim
X% ---------------------------------------
X% This is by far the hairiest and most difficult part of the typesetting task
X% because we have to turn off most of TeX's natural instincts in order to
X% typeset the program text exactly as it appears in the input file.
X% Two macros are defined to pull this off: \fwbtx and \fwverbatimgobble.
X% Their code was inspired by the following sections of "The TeXbook":
X%    Appendix D: Dirty Tricks, 3.Verbatim listing, p.380-382.
X%    Appendix E: Example Formats, p.421.
X% The \fwbtx[ (for "FunnelWeb Begin TeXt") macro does most of the hard work.
X% The liberal use of "%" is because I don't understand TeX well enough to
X% understand when an end of line will cause trouble, and I am playing it safe.
X
X% Before defining the main \fwbtx macro, we have to stash away some definitions
X% in the hidden part of TeX's environment. Let's hope that these "hidden"
X% definitions don't affect anything except what is desired to be affected.
X
X% The tt font in which we wish to set the text has two Latin lurking ligatures!
X% These are ?` and !`. To disable them, we define the left quote when ACTIVE
X% to be defined in such a way as to prevent ligatures. The main TeX text will
X% normally not be exposed to this definition because normally the leftquote
X% character is not active. The \fwbtx macro temporarily makes the left quote
X% character active thus activating the deactivation of left quote ligatures.
X% See The TeXbook p.381.
X{\catcode`\`=\active \gdef`{\relax\lq}}
X
X% TeX is fairly carefree about spaces and so we have to make it more serious.
X% To do so we pull the same trick as above, setting up a definition for active
X% space, but only making space active during the span of the verbatim text.
X% In Plain TeX the active space is defined to be simply a space, but here we
X% define it to be a control space. This ensures that the space cannot
X% be gobbled up by one of TeX's mysterious mechanisms when activated.
X% See The TeXbook, p.381 and p.352.
X{\obeyspaces\global\let =\ }
X
X% Here is the main \fwbtx verbatim text macro.
X% Note: The order in which all these pieces of business have to be done is
X% still a partial mystery to me. Don't fiddle with this stuff unless you
X% think you know what you are doing.
X\def\fwbtx[{%
X%
X% The funnies involved in getting verbatim output are safely housed inside
X% this \begingroup, and the \endgroup in \fwverbatimgobble. Groups are used
X% instead of curly braces because we have to be able to signal the end of
X% this macro with a curly brace.
X\begingroup%
X%
X% \pars at the end of empty lines in the verbatim text won't come out normally
X% because TeX is in vertical mode and they get gobbled up. To prevent this,
X% we force \par to exit vertical mode first. See The TeXbook p.381.
X\def\par{\leavevmode\endgraf}%
X%
X% Activate the leftquote character so as to avoid ligatures (see above).
X\catcode`\`=\active%
X%
X% The \obeylines macro simply defines end of line (^M) to be \par. This ensures
X% that TeX will treat each verbatim line as a new paragraph.
X\obeylines%
X%
X% To get verbatim output, we have to desex all the special characters. This
X% is explained in detail in The TeXbook p.380.
X\def\do##1{\catcode`##1=12 }\dospecials%
X%
X% Activate the space character so as to make TeX treat blanks seriously.
X% This activation invokes an eralier definition (see above).
X\obeyspaces
X%
X% Interparagraph skips do not help the cause.
X% Note: We have to preserve the indentation though, as the code is actually
X% indented in the final output. See \fwodef in an earlier section.
X\parskip=0pt%
X%
X% We typeset the verbatim text in tt font (courier on the Macintosh) for a
X% number of reasons:
X%    - tt font has the same horizontal spacing for each character.
X%    - tt font covers the ASCII character set.
X%    - tt font doesn't have many surprises (e.g. ligatures).
X%    - tt font looks much what you might see on a computer terminal screen.
X\tt%
X%
X% Having set up an environment for verbatim, we are ready to use it.
X% By invoking \fwverbatimgobble, this \fwbtx macro gobbles up text verbatim (as
X% part of the parameter of \fwverbatimgobble) until it sees the termination
X% string "]fwetx=" (the "=" was thrown in to add obscurity as this sequence
X% must never occur in the verbatim text).
X\fwverbatimgobble}
X
X% The \fwverbatimgobble macro exists to allow \fwbtx to bracket verbatim text.
X\def\fwverbatimgobble#1]fwetx={#1\endgroup}
X
X
X% Table of Contents
X% -----------------
X% The five levels of table of contents that FunnelWeb supports are identified
X% by the five letters [A..E]. These are used throughout the following macros.
X
X% The following macros are utilities to the TOC macros to follow.
X\def\fwrule{\medskip\hrule\medskip}
X\def\fwqh{\hskip1.5em\relax}
X\def\fwbeforesec{\penalty-200\bigskip\medskip\par}
X
X% The following macros are used to typeset the table of contents.
X\def\fwtocstart#1{\fwrule\leftline{\fwfontbolda Table of Contents}\fwrule}
X\def\fwtoca#1#2{\leftline{{\bf #1 #2}}}
X\def\fwtocb#1#2{\leftline{\fwqh #1 #2}}
X\def\fwtocc#1#2{\leftline{\fwqh\fwqh #1 #2}}
X\def\fwtocd#1#2{\leftline{\fwqh\fwqh\fwqh #1 #2}}
X\def\fwtoce#1#2{\leftline{\fwqh\fwqh\fwqh\fwqh #1 #2}}
X\def\fwtocfinish#1{\fwrule}
X
X% The following "library" macros define five different strengths of headings
X% which can be used later in the section macros.
X\def\fwliba#1#2{\vfill\eject{\fwfontboldc #1 #2}\penalty200\smallskip}
X\def\fwlibb#1#2{\fwbeforesec{\fwfontboldb #1 #2}\penalty200\smallskip}
X\def\fwlibc#1#2{\fwbeforesec{\fwfontnormb #1 #2}\penalty200\smallskip}
X\def\fwlibd#1#2{\fwbeforesec{\bf          #1 #2}\penalty200}
X\def\fwlibe#1#2{\fwbeforesec{\bf          #1 #2}}
X
X% Here are the macros that actually typeset the section headings throughout
X% the document. The fwlib system has been employed so as to easily allow the
X% user to redefine the strengths of headings to taste. For example, the
X% user could insert in the input document a similar set of definitions to these
X% but with the b..e headings set to \fwlibc. This would tone down the output.
X\def\fwseca#1#2{\fwliba{#1}{#2}}
X\def\fwsecb#1#2{\fwlibb{#1}{#2}}
X\def\fwsecc#1#2{\fwlibc{#1}{#2}}
X\def\fwsecd#1#2{\fwlibd{#1}{#2}}
X\def\fwsece#1#2{\fwlibe{#1}{#2}}
X
X
X% Support for Explicit Typesetting
X% --------------------------------
X% FunnelWeb supports pragmas and other constructs that allow
X% typesetter-independent typesetting commands to be given. The
X% following macros support these features.
X
X% The in-text literal @{sloth@} and emphasise @[walrus@] features.
X\def\fwlit#1{{\tt #1}}
X\def\fwemp#1{{\it #1}}
X
X% The "@p new_page" pragma.
X\def\fwnewpage{\vfill\eject}
X
X% The "@p vskip Nmm" pragma.
X\def\fwvskip#1{\null\vskip #1mm}
X
X% The "@p title <font> <align> <text>" pragma.
X\def\fwfontnormal#1{{\fwfontnorm {#1}}}
X\def\fwfonttitle#1{{\fwfontboldd {#1}}}
X\def\fwfontsmalltitle#1{{\fwfontboldb {#1}}}
X\def\fwleftline#1{\leftline{#1}}
X\def\fwcenterline#1{\centerline{#1}}
X\def\fwrightline#1{\rightline{#1}}
X
X
X% Support for Old FunnelWeb
X% -------------------------
X% The following macros were used extensively in the first version of
X% FunnelWeb and are retained so that these older input files will still
X% typeset cleanly.
X\def\p#1{{\tt #1}}  % P for Program text.
X\def\flagpage#1#2{
X   \null
X   \vfill
X   \centerline{\fwfontboldd #1}

X            GNU GENERAL PUBLIC LICENSE
X               Version 2, June 1991
X
X Copyright (C) 1989, 1991 Free Software Foundation, Inc.
X                          675 Mass Ave, Cambridge, MA 02139, USA
X Everyone is permitted to copy and distribute verbatim copies
X of this license document, but changing it is not allowed.
X
X                Preamble
X
X  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
XFoundation'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.
X
X  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.
X
X  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.
X
X  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.
X
X  We protect your rights with two steps: (1) copyright the software, and
X(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
X
X  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.
X
X  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.
X
X  The precise terms and conditions for copying, distribution and
modification follow.
X
X            GNU GENERAL PUBLIC LICENSE
X   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
X
X  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".
X
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.
X
X  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.
X
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.
X
X  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:
X
X    a) You must cause the modified files to carry prominent notices
X    stating that you changed the files and the date of any change.
X
X    b) You must cause any work that you distribute or publish, that in
X    whole or in part contains or is derived from the Program or any
X    part thereof, to be licensed as a whole at no charge to all third
X    parties under the terms of this License.
X
X    c) If the modified program normally reads commands interactively
X    when run, you must cause it, when started running for such
X    interactive use in the most ordinary way, to print or display an
X    announcement including an appropriate copyright notice and a
X    notice that there is no warranty (or else, saying that you provide
X    a warranty) and that users may redistribute the program under
X    these conditions, and telling the user how to view a copy of this
X    License.  (Exception: if the Program itself is interactive but
X    does not normally print such an announcement, your work based on
X    the Program is not required to print an announcement.)
X
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.
X
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.
X
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.
X
X  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:
X
X    a) Accompany it with the complete corresponding machine-readable
X    source code, which must be distributed under the terms of Sections
X    1 and 2 above on a medium customarily used for software interchange; or,
X
X    b) Accompany it with a written offer, valid for at least three
X    years, to give any third party, for a charge no more than your
X    cost of physically performing source distribution, a complete
X    machine-readable copy of the corresponding source code, to be
X    distributed under the terms of Sections 1 and 2 above on a medium
X    customarily used for software interchange; or,
X
X    c) Accompany it with the information you received as to the offer
X    to distribute corresponding source code.  (This alternative is
X    allowed only for noncommercial distribution and only if you
X    received the program in object code or executable form with such
X    an offer, in accord with Subsection b above.)
X
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.
X
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.
X
X  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.
X
X  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.
X
X  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.
X
X  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.
X
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.
X
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.
X
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
X
X  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.
X
X  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.
X
XEach 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
XFoundation.
X
X  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.
X
X                NO WARRANTY
X
X  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
XFOR 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.
X
X  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.
X
X             END OF TERMS AND CONDITIONS
X
X    Appendix: How to Apply These Terms to Your New Programs
X
X  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.
X
X  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.
X
X    <one line to give the program's name and a brief idea of what it does.>
X    Copyright (C) 19yy  <name of author>
X
X    This program is free software; you can redistribute it and/or modify
X    it under the terms of the GNU General Public License as published by
X    the Free Software Foundation; either version 2 of the License, or
X    (at your option) any later version.
X
X    This program is distributed in the hope that it will be useful,
X    but WITHOUT ANY WARRANTY; without even the implied warranty of
X    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
X    GNU General Public License for more details.
X
X    You should have received a copy of the GNU General Public License
X    along with this program; if not, write to the Free Software
X    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
X
Also add information on how to contact you by electronic and paper mail.
X
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
X
X    Gnomovision version 69, Copyright (C) 19yy name of author
X    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
X    type `show w'.
X    This is free software, and you are welcome to redistribute it
X    under certain conditions; type `show c' for details.
X
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.
X
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:
X
X  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
X  `Gnomovision' (which makes passes at compilers) written by James Hacker.
X
X  <signature of Ty Coon>, 1 April 1989
X  Ty Coon, President of Vice
X
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.
