+% This is CSTY.STY as received by email at december 1990
+%
+% The cprog macros allow programs in C, C++, Pascal, and Modula-2 to be
+% included directly into TeX documents.  Program text is set in a Roman
+% font, comments in slanted, and strings in typewriter.  Operators such as
+% <= are optionally combined into single symbols like $\le$.  Keywords are
+% *not* emphasised---I find this ugly and distracting.  (By purest
+% coincidence it would also be very hard to do.)
+%
+% These macros can be \input in plain TeX or used as a style file in LaTeX.
+% They provide a convenient alternative to tgrind, particularly for program
+% fragments embedded in documents.  Full instructions for use appear in the
+% macro package itself.
+%

+% BEGIN: cprog.tex (or cprog.sty) - formatting of C programs
+% By \'Eamonn McManus <emcmanus@cs.tcd.ie>.  This file is not copyrighted.
+% $Id: cprog.tex,v 1.4 90/09/12 23:21:26 emcmanus Exp $
+ 
+% This allows C programs to be formatted directly by TeX.  It can be
+% invoked by \cprogfile{filename} or (in LaTeX) \begin{cprog} ...
+% \end{cprog} or (in plain TeX) \cprog ... \end{cprog}.  In LaTeX, the
+% alternative form \begin{cprog*} is allowed, where spaces in C strings
+% are printed using the `square u' character (like LaTeX {verbatim*}).
+% In plain TeX, you have to use \csname cprog*\endcsname for this (sorry).
+% If you are using \cprogfile, say \cprogttspacetrue beforehand if you
+% want this effect.
+ 
+% The formatting is (necessarily) simple.  C text is set in a normal Roman
+% font, comments in a slanted font, and strings in a typewriter font, with
+% spaces optionally made visible as the `square u' symbol.  Tabs are
+% expanded to four spaces (this does not look good when comments are
+% aligned to the right of program text).  Some pairs of input characters
+% appear as single output characters: << <= >> >= != -> are respectively
+% TeX's \ll \le \gg \ge \ne \rightarrow.  Say \cprogpairsfalse to disable
+% this.
+ 
+% You can escape to TeX within cprog text by defining an escape character.
+% The character @ is suitable for C and Pascal.  I have not tested other
+% characters so they may interact badly with their existing definitions here.
+% To define @ as the escape character, do \cprogescape@.  Then within text
+% you can do @ followed by TeX commands.  These commands will be in a TeX
+% group with the \catcodes of \{}% as normal.  The commands are terminated
+% by a newline, which is not considered part of the program text.
+ 
+% The fonts below can be changed to alter the setting of the various parts
+% of the program.  The \cprogbaselineskip parameter can be altered to
+% change the line spacing.  LaTeX's \baselinestretch is taken into account
+% too.  The indentation applied to the whole program is \cprogindent,
+% initially 0.  Before and after the program there are skips of
+% \beforecprogskip and \aftercprogskip; the default values are \parskip
+% and 0 respectively (since there will often be a \parskip after the
+% program anyway).
+ 
+% If the source text is Pascal or Modula-2, say \pascaltrue or \modulatrue
+% (respectively) before formatting it.  This makes (* *) be recognised for
+% comments instead of /* */.  Braces {} are also recognised for Pascal.
+% \pascalfalse or \modulafalse as appropriate restores the default of C.
+ 
+% This package works by making a large number of characters active.  Since
+% even spaces are active, it is possible to examine the next character in
+% a macro by making it a parameter, rather than using \futurelet as one
+% would normally do.  This is more convenient, but the coding does mean
+% that if the next character itself wants to examine a character it may
+% look at a token from the macro rather than the input text.  I think that
+% all cases that occur in practice have been looked after.
+ 
+% The macros could still do with some work.  For example, the big macro
+% defined with [] taking the place of {} could be recoded to use {} and so
+% be more legible.  The internal macros etc should have @ in their names,
+% and should be checked against LaTeX macros for clashes.
+ 
+% Allow multiple inclusion to go faster.

+underscore.sty    12-Oct-2001  Donald Arseneau
+
+Features:
+~~~~~~~~~
+\_ prints an underscore so that the hyphenation of constituent words
+is not affected and hyphenation is permitted after the underscore.
+For example, "compound\_fracture" hyphenates as com- pound_- frac- ture.
+If you prefer the underscore to break without a hyphen (but still with 
+the same rules for explicit hyphen-breaks) then use the [nohyphen]
+package option.
+
+A simple _  acts just like \_ in text mode, but makes a subscript in 
+math mode: activation_energy $E_a$
+
+Both forms use an underscore character if the font encoding contains
+one (e.g., "\usepackage[T1]{fontenc}" or typewriter fonts in any encoding),
+but they use a rule if the there is no proper character.
+
+Deficiencies:
+~~~~~~~~~~~~~
+The skips and penalties ruin any kerning with the underscore character
+(when a character is used).  However, there doesn't seem to be much, if
+any, such kerning in the ec fonts, and there is never any kerning with
+a rule.
+
+You must avoid "_" in file names and in cite or ref tags, or you must use 
+the babel package, with its active-character controls, or you must give 
+the [strings] option, which attempts to redefine several commands (and 
+may not work perfectly).  Even without the [strings] option or babel, you 
+can use occasional underscores like: "\include{file\string_name}".
+
+Option: [strings]
+~~~~~~~~~~~~~~~~~
+The default operation is quite simple and needs no customization; but
+you must avoid using "_" in any place where LaTeX uses an argument as
+a string of characters for some control function or as a name.  These
+include the tags for \cite and \ref, file names for \input, \include,
+and \includegraphics, environment names, counter names, and placement
+parameters (like "[t]").  The problem with these contexts is that they
+are `moving arguments' but LaTeX does not `switch on' the \protect
+mechanism for them.
+
+If you need to use the underscore character in these places, the package
+option [strings] is provided to redefine commands taking a string argument
+so that the argument is protected (with \protect -> \string).  The list
+of commands is given in "\UnderscoreCommands", with "\do" before each,
+covering \cite, \ref, \input, and their variants.  Not included are many
+commands regarding font names, everything with counter names, environment
+names, page styles, and versions of \ref and \cite defined by external
+packages (e.g. \vref and \citeyear).
+
+You can add to the list of supported commands by defining \UnderscoreCommands
+before loading this package; e.g.
+
+   \usepackage{chicago}
+   \newcommand{\UnderscoreCommands}{%   (\cite already done)
+     \do\citeNP \do\citeA \do\citeANP \do\citeN \do\shortcite
+     \do\shortciteNP \do\shortciteA \do\shortciteANP \do\shortciteN
+     \do\citeyear \do\citeyearNP
+   }
+   \usepackage[strings]{underscore}
+
+Not all commands can be supported this way!  Only commands that take a
+string argument *first* can be protected.  One optional argument before
+the string argument is also permitted, as exemplified by \cite: both
+\cite{tags} and \cite[text]{tags} are allowed.  A command like
+\@addtoreset which takes two counter names as arguments could not
+be protected by adding it to \UnderscoreCommands.
+
+!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+!! When you use the [strings] option, you must load this package !!
+!! last (or nearly last).                                        !!
+!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+There are two reasons: 1) The redefinitions done for protection must come
+after other packages define their customized versions of those commands.
+2) The [strings] option requires the _ character to be activated immediately
+in order for the cite and ref tags to be read properly from the .aux file
+as plain strings, and this catcode setting might disrupt other packages.
+
+The babel package implements a protection mechanism for many commands,
+and will be a complete fix for most documents without the [strings] option.
+Many add-on packages are compatible with babel, so they will get the
+strings protection also.  However, there are several commands that are 
+not covered by babel, but can easily be supported by the [strings] and 
+\UnderscoreCommands mechanism.  Beware that using both [strings] and babel 
+may lead to conflicts, but does appear to work (load babel last).
+
+Implementation Notes:
+~~~~~~~~~~~~~~~~~~~~~
+The first setting of "_" to be an active character is performed in a local
+group so as to not interfere with other packages.  The catcode setting
+is repeated with \AtBeginDocument so the definition is in effect for the
+text.  However, the catcode setting is repeated immediately when the
+[strings] option is detected.
+
+The definition of the active "_" is essentially:
+       \ifmmode \sb \else \BreakableUnderscore \fi
+where "\sb" retains the normal subscript meaning of "_" and where
+"\BreakableUnderscore" is essentially "\_".  The rest of the definition
+handles the "\protect"ion without causing \relax to be inserted before
+the character.
+
+\BreakableUnderscore uses "\nobreak\hskip\z@skip" to separate the
+underscore from surrounding words, thus allowing TeX to hyphenate them,
+but preventing free breaks around the underscore. Next, it checks the
+current font family, and uses the underscore character from tt fonts or
+otherwise \textunderscore (which is a character or rule depending on
+the font encoding).  After the underscore, it inserts a discretionary
+hyphenation point as "\usc@dischyph", which is usually just "\-"
+except that it still works in the tabbing environment, although it
+will give "\discretionary{}{}{}" under the [nohyphen] option.  After
+that, another piece of non-breaking interword glue is inserted. 
+Ordinarily, the comparison "\ifx\f@family\ttdefault" will always fail 
+because \ttdefault is `long' where \f@family is not (boooo hisss), but 
+\ttdefault is redefined to be non-long by "\AtBeginDocument".
+
+The "\_" command is then defined to use "\BreakableUnderscore".
+
+If the [strings] option is not given, then that is all!
+
+Under the [strings] option, the list of special commands is processed to:
+- retain the original command as \US_command (\US_ref)
+- redefine the command as \US@prot\US_command for ordinary commands
+  (\ref -> \US@prot\US_ref) or as \US@protopt\US_command when an optional
+  argument is possible (\bibitem -> \US@protopt\US_bibitem).
+- self-protecting commands (\cite) retain their self-protection.
+Diagnosing the state of the pre-existing command is done by painful
+contortions involving \meaning.
+
+\US@prot and \US@protopt read the argument, process it with \protect
+enabled, then invoke the saved \US_command.

+% zrl.sty  ver 1.4   02-Mar-1999   Donald Arseneau   asnd@reg.triumf.ca
+%
+% This package defines "\zrl", a form of "\verb" that allows linebreaks,
+% and can often be used in the argument to another command.  It can be
+% configured to print in different formats, and is particularly useful for
+% hypertext links, email addresses, directories/paths, etc.  The font may
+% be selected using the "\zrlstyle" command and pre-defined text can be
+% stored with the "\zrldef" command. New zrl-like commands can be defined,
+% and a "\path" command is provided this way.
+%
+% Usage:    Conditions:
+% \zrl{ }   If the argument contains any "%", "#", or "^^", or ends with
+%           "\", it can't be used in the argument to another command.
+%           The argument must not contain unbalanced braces.
+% \zrl|  |  ...where "|" is any character not used in the argument and not
+%           "{" or a space.  The same restrictions as above except that the
+%           argument may contain unbalanced braces.
+% \xyz      for "\xyz" a defined-zrl;  this can be used anywhere, no matter
+%           what characters it contains.
+%
+% The "\zrl" command is fragile, and its argument is likely to be very
+% fragile, but a defined-zrl is robust.
+%
+% Package Option:  obeyspaces
+% Ordinarily, all spaces are ignored in the zrl-text.  The "[obeyspaces]"
+% option allows spaces, but may introduce spurious spaces when a zrl
+% containing "\" characters is given in the argument to another command.
+% So if you need to obey spaces you can say "\usepackage[obeyspaces]{zrl}",
+% and if you need both spaces and backslashes, use a `defined-zrl' for
+% anything with "\".
+%
+% Package Option:  hyphens
+% Ordinarily, breaks are not allowed after "-" characters because this
+% leads to confusion. (Is the "-" part of the address or just a hyphen?)
+% The package option "[hyphens]" allows breaks after explicit hyphen
+% characters.  The "\zrl" command will *never ever* hyphenate words.
+%
+% Package Option:  spaces
+% Likewise, breaks are not usually allowed after spaces under the
+% "[obeyspaces]" option, but giving the options "[obeyspaces,spaces]"
+% will allow breaks at those spaces.
+%
+% Package Option:  T1
+% This signifies that you will be using T1-encoded fonts which contain
+% some characters missing from most older (OT1) encoded TeX fonts.  This
+% changes the default definition for "\zrlstyle{rm}".
+%
+% Defining a defined-zrl:
+% Take for example the email address "myself%node@gateway.net" which could
+% not be given (using "\zrl" or "\verb") in a caption or parbox due to the
+% percent sign.  This address can be predefined with
+%    \zrldef{\myself}\zrl{myself%node@gateway.net}   or
+%    \zrldef{\myself}\zrl|myself%node@gateway.net|
+% and then you may use "\myself" instead of "\zrl{myself%node@gateway.net}"
+% in an argument, and even in a moving argument like a caption because a
+% defined-zrl is robust.
+%
+% Style:
+% You can switch the style of printing using "\zrlstyle{tt}", where "tt"
+% can be any defined style.  The pre-defined styles are "tt", "rm", "sf",
+% and "same" which all allow the same linebreaks but different fonts --
+% the first three select a specific font and the "same" style uses the
+% current text font.  You can define your own styles with different fonts
+% and/or line-breaking by following the explanations below.  The "\zrl"
+% command follows whatever the currently-set style dictates.
+%
+% Alternate commands:
+% It may be desireable to have different things treated differently, each
+% in a predefined style; e.g., if you want directory paths to always be
+% in tt and email addresses to be rm, then you would define new zrl-like
+% commands as follows:
+%
+%    \newcommand\email{\begingroup \zrlstyle{rm}\Zrl}
+%    \newcommand\directory{\begingroup \zrlstyle{tt}\Zrl}
+%
+% You must follow this format closely, and NOTE that the final command is
+% "\Zrl", not "\zrl".  In fact, the "\directory" example is exactly the
+% "\path" definition which is pre-defined in the package.  If you look
+% above, you will see that "\zrl" is defined with
+%    \newcommand\zrl{\begingroup \Zrl}
+% I.e., using whatever zrl-style has been selected.
+%
+% You can make a defined-zrl for these other styles, using the usual
+% "\zrldef" command as in this example:
+%
+%    \zrldef{\myself}{\email}{myself%node.domain@gateway.net}
+%
+% which makes "\myself" act like "\email{myself%node.domain@gateway.net}",
+% if the "\email" command is defined as above.  The "\myself" command
+% would then be robust.
+%
+% Defining styles:
+% Before describing how to customize the printing style, it is best to
+% mention something about the unusual implementation of "\zrl".  Although
+% the material is textual in nature, and the font specification required
+% is a text-font command, the text is actually typeset in *math* mode.
+% This allows the context-sensitive linebreaking, but also accounts for
+% the default behavior of ignoring spaces.  Now on to defining styles.
+%
+% To change the font or the list of characters that allow linebreaks, you
+% could redefine the commands "\ZrlFont", "\ZrlBreaks", "\ZrlSpecials" etc.
+% directly in the document, but it is better to define a new `zrl-style'
+% (following the example of "\zrl@ttstyle" and "\zrl@rmstyle") which defines
+% all of "\ZrlBigbreaks", "\ZrlNoBreaks", "\ZrlBreaks", "\ZrlSpecials", and
+% "\ZrlFont".
+%
+% Changing font:
+% The "\ZrlFont" command selects the font.  The definition of "\ZrlFont"
+% done by the pre-defined styles varies to cope with a variety of LaTeX
+% font selection schemes, but it could be as simple as "\def\ZrlFont{\tt}".
+% Depending on the font selected, some characters may need to be defined
+% in the "\ZrlSpecials" list because many fonts don't contain all the
+% standard input characters.
+%
+% Changing linebreaks:
+% The list of characters that allow line-breaks is given by "\ZrlBreaks"
+% and "\ZrlBigBreaks", which have the format "\do\c" for character "c".
+% The differences are that `BigBreaks' have a lower penalty and have
+% different breakpoints when in sequence (as in "http://"): `BigBreaks'
+% are treated as mathrels while `Breaks' are mathbins (see The TeXbook,
+% p.170). In particular, a series of `BigBreak' characters will break at
+% the end and only at the end; a series of `Break' characters will break
+% after the first and after every following *pair*; there will be no
+% break after a `Break' character if a `BigBreak' follows.  In the case
+% of "http://" it doesn't matter whether ":" is a `Break' or `BigBreak' --
+% the breaks are the same in either case; but for DECnet nodes with "::"
+% it is important to prevent breaks *between* the colons, and that is why
+% colons are `BigBreaks'.
+%
+% It is possible for characters to prevent breaks after the next following
+% character (I use this for parentheses).  Specify these in "\ZrlNoBreaks".
+%
+% You can do arbitrarily complex things with characters by making them
+% active in math mode (mathcode hex-8000) and specifying the definition(s)
+% in "\ZrlSpecials".  This is used in the rm and sf styles for OT1 font
+% encoding to handle several characters that are not present in those
+% computer-modern style fonts.  See the definition of "\Zrl@do", which
+% is used by both "\zrl@rmstyle" and "\zrl@sfstyle"; it handles missing
+% characters via "\ZrlSpecials".  The nominal format for setting each
+% special character "c" is: "\do\c{<definition>}", but you can include
+% other definitions too.
+%
+%
+% If all this sounds confusing ... well, it is!  But I hope you won't need
+% to redefine breakpoints -- the default assignments seem to work well for
+% a wide variety of applications.  If you do need to make changes, you can
+% test for breakpoints using regular math mode and the characters "+=(a".
+%
+% Yet more flexibility:
+% You can also customize the verbatim text by defining "\ZrlRight" and/or
+% "\ZrlLeft", e.g., for ISO formatting of zrls surrounded by "<  >", define
+%
+%    \renewcommand\zrl{\begingroup \def\ZrlLeft{<zrl: }\def\ZrlRight{>}%
+%        \zrlstyle{tt}\Zrl}
+%
+% The meanings of "\ZrlLeft" and "\ZrlRight" are *not* reproduced verbatim.
+% This lets you use formatting commands there, but you must be careful not
+% to use TeX's special characters ("\^_%~#$&{}" etc.) improperly.
+% You can also define "\ZrlLeft" to reprocess the verbatim text, but the
+% format of the definition is special:
+%
+%    \def\ZrlLeft#1\ZrlRight{ ... do things with #1 ... }
+%
+% Yes, that is "#1" followed by "\ZrlRight" then the definition.  For
+% example, to put a hyperTeX hypertext link in the DVI file:
+%
+%    \def\ZrlLeft#1\ZrlRight{\special{html:<a href="#1">}#1\special{html:</a>}}
+%
+% Using this technique, zrl.sty can provide a convenient interface for
+% performing various operations on verbatim text.  You don't even need
+% to print out the argument!  For greatest efficiency in such obscure
+% applications, you can define a null zrl-style where all the lists like
+% "\ZrlBreaks" are empty.
