 -- Style Sheet: 68000 (68000.ssh)
     Althought designed at the origin for the 68k's assembler, this style sheet seems to handle rather well other dialects.

 -- Style Sheet: a2ps configuration file (a2psrc.ssh)
     Meant to print files such as a2ps.cfg, or .a2ps/a2psrc, etc.

 -- Style Sheet: a2ps style sheet (ssh.ssh)
     Second level of highligthing (option -g)) substitutes the LaTeX symbols.

 -- Style Sheet: Ada (ada.ssh)
     This style sheets cover Ada 95.  If you feel the need for Ada 83, you'll have to design another style sheet.

 -- Style Sheet: ASN.1 (asn1.ssh)
     Written by Philippe Coucaud. ASN.1 (Abstract Syntax Notation One) is used to define the protocol data units (PDUs) of all application layer protocols to date.

 -- Style Sheet: Autoconf (autoconf.ssh)
     Suitable for both configure.in and library m4 files.

 -- Style Sheet: AWK (awk.ssh)
     Written by Edward Arthur. This style is devoted to the AWK pattern scanning and processing language. It is supposed to support classic awk, nawk and gawk.

     Written by Philippe Coucaud. B is a formal specification method mostly used to describe critical systems.  It is based on the mathematical sets theory.

 -- Style Sheet: BC (bc.ssh)
     bc is an arbitrary precision calculator language.

 -- Style Sheet: Bourne Shell (sh.ssh)
     Some classical program names, or builtin, are highlighted in the second level of pretty-printing.

 -- Style Sheet: C (c.ssh)
     This style does not highlight the function definitions. Another style which highlights them, GNUish C, is provided (gnuc.ssh). It works only if you respect some syntactic conventions.

 -- Style Sheet: C Shell (csh.ssh)
     Written by Jim Diamond. Some classical program names, and/or builtins, are highlighted in the second level of pretty-printing.

 -- Style Sheet: C# (csharp.ssh)
     Written by Karen Christenson. This style is for the .NET object-oriented language C#, and is based on the C# Language Specification published in 2002 by Microsoft in the MSDN library. XML comments are mapped to strong comments, and any other comment is a plain comment. The C style-sheet was not selected as an ancestor in order to treat a struct the same as a class or an interface.  The CPP style-sheet was not selected as an ancestor because C# set of preprocessor directives is much smaller. Keywords, XML comments, preprocessor directives, label statements, and [] style attributes are high-lighted.

 -- Style Sheet: C++ (cxx.ssh)
     Should handle all known variations of C++.  Most declarations (classes etc.) are not highlighted as they should be.  Please, step forward!

 -- Style Sheet: CAML (caml.ssh)
     This style is obsolete: use OCaml instead.

 -- Style Sheet: ChangeLog (chlog.ssh)
     This style covers the usual ChangeLog files.

 -- Style Sheet: Claire (claire.ssh)
     Claire is a high-level functional and object-oriented language with advanced rule processing capabilities. It is intended to allow the programmer to express complex algorithms with fewer lines and in an elegant and readable manner.

     To provide a high degree of expressivity, Claire uses:

       - A very rich type system including type intervals and second-order types (with dual static/dynamic typing),

       - Parametric classes and methods,

       - An object-oriented logic with set extensions,

       - Dynamic versioning that supports easy exploration of search spaces.

     To achieve its goal of readability, Claire uses

       - set-based programming with an intuitive syntax,

       - simple-minded object-oriented programming,

       - truly polymorphic and parametric functional programming,

       - a powerful-yet-readable extension of DATALOG to express logical conditions,

       - an entity-relation approach with explicit relations, inverses, unknown values and relational

       - operations.

     More information on claire can be found on http://www.ens.fr/~laburthe/claire.html,claire home page.

 -- Style Sheet: Common Lisp (clisp.ssh)
     Written by Juliusz Chroboczek. It is not very clear what should be considered as a `keyword' in Common Lisp.  I like binders, control structures and declarations to be highlighted, but not assignments.

     Names of defstructs are not highlighted because this would not work with defstruct options.

 -- Style Sheet: Coq Vernacular (coqv.ssh)
     This style is devoted to the Coq v 5.10 vernacular language.

 -- Style Sheet: CORBA IDL (cidl.ssh)
     Written by Bob Phillips. A first attempt at a style sheet for OMG CORBA IDL. I believe I captured all the keywords for CORBA 2.2 IDL. I also stole code from gnuc.ssh to print the method names in bold face.  I'm not sure I quite like my own choices for Keyword_strong and Keyword, so I'm looking for feedback. Note that, as with gnuc.ssh, for a method name to be noted as such, the left parenthesis associated with the argument list for the method must appear on the same line as the method name.

 -- Style Sheet: CPP (cpp.ssh)
     C traditional preprocessor handling, mostly meant to be inherited.

 -- Style Sheet: dc_shell (dc_shell.ssh)
     Written by Philippe Le Van. Synopsys Design Compiler is a synthesis tool used by electronic companies for the design of their chips. This sheet is very incomplete, we have a lot of keywords to add, eventually options to highlight... The Label_strong style is used for commands which change the design.

 -- Style Sheet: Eiffel (eiffel.ssh)
     Eiffel is an object oriented language that also includes a comprehensive approach to software construction: a method.

     The language itself is not just a programming language but also covers analysis, design and implementation.

     Heavy highlight uses symbols to represent common math operators.

 -- Style Sheet: Emacs Lisp (elisp.ssh)
     Written by Didier Verna. This style sheet includes support for some extensions dumped with XEmacs.

 -- Style Sheet: Encapsulated PostScript (eps.ssh)

 -- Style Sheet: Extended Tcl (tclx.ssh)
     Written by Phil Hollenback. Extensions to plain Tcl.

 -- Style Sheet: Fortran (fortran.ssh)
     Written by Denis Girou,  Alexander Mai. There are several Fortran dialects, depending whether, on the one hand, you use Fortran 77 or Fortran 90/95, and, on the other hand, Fixed form comments, or Free form comments.

     The style sheets for77kwds and for90kwds implements keywords only, while the style sheets for-fixed and for-free implements comments only.

     This style sheet tries to support any of the various flavors (Fortran 77/90/95, fixed or free form).  For more specific uses, you should use either:

       - for77-fixed, for Fortran 77 fixed form,

       - for77-free, for Fortran 77 free form,

       - for90-fixed, for Fortran 90/95 fixed form,

       - for90-free, for Fortran 90/95 free form.

 -- Style Sheet: Fortran 77 Fixed (for77-fixed.ssh)
     Written by Denis Girou,  Alexander Mai. Dedicated to Fortran 77 in fixed form, i.e., comments are lines starting with c, C, or *, and only those lines are comments.

 -- Style Sheet: Fortran 77 Free (for77-free.ssh)
     Written by Denis Girou,  Alexander Mai. Dedicated to Fortran 77 in free form, i.e., comments are introduced by ! anywhere on the line, and nothing else is a comment.

 -- Style Sheet: Fortran 77 Keywords (for77kwds.ssh)
     Written by Denis Girou,  Alexander Mai. This sheet implements only Fortran 77 keywords, and avoids implementing comments support. This is to allow for implementation of either fixed or free source form.

     See the documentation of the style sheet fortran for more details.

 -- Style Sheet: Fortran 90 Fixed (for90-fixed.ssh)
     Written by Denis Girou,  Alexander Mai. Dedicated to Fortran 90/95 in fixed form, i.e., comments are lines starting with c, C, or *, and only those lines are comments.

 -- Style Sheet: Fortran 90 Free (for90-free.ssh)
     Written by Denis Girou,  Alexander Mai. Dedicated to Fortran 90/95 in free form, i.e., comments are introduced by ! anywhere on the line, and nothing else is a comment.

 -- Style Sheet: Fortran 90 Keywords (for90kwds.ssh)
     Written by Denis Girou,  Alexander Mai. This sheet implements the superset which Fortran 90 and Fortran 95 provide over Fortran 77.

     See the documentation of the style sheet fortran for more details.

 -- Style Sheet: Fortran Fixed (for-fixed.ssh)
     Written by Denis Girou,  Alexander Mai. Implements comments of Fortran in fixed form, i.e., comments are lines starting with c, C, or *, and only those lines are comments. No other highlighting is done.

     See the documentation of the style sheet fortran for more details.

 -- Style Sheet: Fortran Free (for-free.ssh)
     Written by Denis Girou,  Alexander Mai. Dedicated to Fortran in free form, i.e., comments are introduced by ! anywhere on the line, and nothing else is a comment.

 -- Style Sheet: GNUish C (gnuc.ssh)
     Declaration of functions are highlighted only if you start the function name in the first column, and it is followed by an opening parenthesis.  In other words, if you write

          int main (void)

     it won't work.  Write:

          int
          main (void)

 -- Style Sheet: GNUMakefile (gmake.ssh)
     Written by Alexander Mai. Special tokens of GNUmakefiles and non terminal declarations are highlighted.

 -- Style Sheet: Haskell (haskell.ssh)
     Written by Ilya Beylin. Haskell: non-strict functional programming language http::/www.haskell.org/

 -- Style Sheet: HTML (html.ssh)
     Written by  Wesley J. Chun. This style is meant to pretty print HTML source files, not to simulate its interpretation (i.e., <bold>foo</bold> does not print foo in bold).  If you really meant to print the result of the HTML file interpreted, then you should turn the delegations on, and make sure a2ps has HTML delegations.

 -- Style Sheet: IDL (idl.ssh)
     Written by Robert S. Mallozzi,  Manfred Schwarb. Style sheet for IDL 5.2 (Interactive Data Language). Obsolete routines are not supported. http://www.rsinc.com.

 -- Style Sheet: InstallShield 5 (is5rul.ssh)
     Written by Alex. InstallShield5 _TM_ RUL script.

 -- Style Sheet: Java (java.ssh)
     Written by Steve Alexander. Documentation comments are mapped to strong comments, and any other comment is plain comment.

 -- Style Sheet: JavaScript (js.ssh)
     Written by Scott Pakin. Keywords used are everything listed in the Client-Side JavaScript Reference 1.3, plus "undefined" (why isn't that listed?) and "prototype".  I omitted the semi-standard a2ps optional operators for equality, because JavaScript's use of both strict- and non-strict equality might ambiguate the output.  Finally, regular expressions are formatted like strings.

 -- Style Sheet: LACE (lace.ssh)
     This is meant for the Eiffel equivalent of the Makefiles.

 -- Style Sheet: Lex (lex.ssh)
     In addition to the C constructs, it highlights the declaration of states, and some special % commands.

 -- Style Sheet: Lout (lout.ssh)
     Written by Jean-Baptiste Nivoit. This is the style for Lout files.

 -- Style Sheet: Mail Folder (mail.ssh)
     To use from elm and others, it is better to specify -g -Email, since the file sent to printer is no longer truly a mail folder. This style also suits to news.  --strip options are also useful (they strip "useless" headers).

     Whenever the changes of encoding are clear, a2ps sets itself the encoding for the parts concerned.

     Tag 1 is the subject, and Tag 2 the author of the mail/news.

     Note: This style sheet is _very_ difficult to write.  Please don't report behavior you don't like.  Just send me improvements, or write a Bison parser for mails.

 -- Style Sheet: Makefile (make.ssh)
     Special tokens, and non terminal declarations are highlighted.

 -- Style Sheet: Management Information Base (mib.ssh)
     Written by Kelly Wiles. The MIB file is of ASN.1 syntax.

     Written by Richard J Mathar. Some classical program names, and/or builtins, are highlighted in the second level of pretty-printing.

 -- Style Sheet: masm (nasm.ssh)
     Written by Aleksandar Veselinovic. This style highlights MASM ASM code.

 -- Style Sheet: Matlab (matlab.ssh)
     Written by Joakim Lübeck. This style highlights function definitions and a limited number of keywords, mostly control constructs, and is therefore usable for many Matlab versions. Special care have been taken to distinguish string delimiters from the transpose operator (which is the same symbol) and to recognize comments.

 -- Style Sheet: MATLAB 4 (matlab4.ssh)
     Written by Marco De la Cruz. Note that comments in the code should have a space after the %.

 -- Style Sheet: Modula 2 (modula2.ssh)
     Written by Peter Bartke.

 -- Style Sheet: Modula 3 (modula3.ssh)
     Modula-3 is a member of the Pascal family of languages. Designed in the late 1980s at Digital Equipment Corporation and Olivetti, Modula-3 corrects many of the deficiencies of Pascal and Modula-2 for practical software engineering. In particular, Modula-3 keeps the simplicity of type safety of the earlier languages, while providing new facilities for exception handling, concurrency, object-oriented programming, and automatic garbage collection. Modula-3 is both a practical implementation language for large software projects and an excellent teaching language.

     This sheet was designed based on http://www.research.digital.com/SRC/modula-3/html/home.html,Modula 3 home page.

 -- Style Sheet: o2c (o2c.ssh)

 -- Style Sheet: Oberon (oberon.ssh)
     Created by N. Wirth, Oberon is the successor of the Pascal and Modula-2 family of programming languages. It was specifically designed for systems programming, and was used to create the Oberon system in cooperation with J. Gutknecht. A few years later, the Oberon language was extended with additional object-oriented features to result in the programming language Oberon-2.

     Implementation of the sheet based on http://www.math.tau.ac.il/~laden/Oberon.html,The Oberon Reference Site.

 -- Style Sheet: Objective C (objc.ssh)
     Written by Paul Shum.

     Written by Pierre Mareschal. 18-MAR-97 For comments, support for -- /*..*/ and //. This style is to be checked.

 -- Style Sheet: Pascal (pascal.ssh)
     The standard Pascal is covered by this style. But some extension have been added too, hence modern Pascal programs should be correctly handled. Heavy highlighting maps mathematical symbols to their typographic equivalents.

 -- Style Sheet: Perl (perl.ssh)
     Written by Denis Girou. As most interpreted languages, Perl is very free on its syntax, what leads to significant problems for a pretty printer.  Please, be kind with our try.  Any improvement is most welcome.

 -- Style Sheet: PHP (php.ssh)
     Written by Hartmut Holzgraefe. This is a a2ps stylesheet for PHP syntax highlighting (just the PHP part, HTML is left 'as is'). This is my first try on a2ps stylesheets. It works OK for me. If it doesn't come up to your expectatios, then please tell me.

 -- Style Sheet: pic16f84 (pic16f84.ssh)
     Written by Aleksandar Veselinovic. This style highlights PIC16F84 ASM code.

     Support for Adobe's PPD files.

 -- Style Sheet: Pov-Ray (pov.ssh)
     Written by Jean-Baptiste Nivoit. Should handle Persistence Of Vision input files.

 -- Style Sheet: PreScript (pre.ssh)
     This style defines commands in the canonic syntax of a2ps. It is meant to be used either as an input language, and to highlight the table of contents etc.

     It can be a good choice of destination language for people who want to produce text to print (e.g. pretty-printing, automated documentation etc.) but who definitely do not want to learn PostScript, nor to require the use of LaTeX.

 -- Style Sheet: PreTeX (pretex.ssh)
     This style sheets provides LaTeX-like commands to format text. It is an alternative to the PreScript style sheet, in which formating commands are specified in a more a2ps related syntax.

     It provides by the use of LaTeX like commands, a way to describe the pages that this program should produce.

 -- Style Sheet: Prolog (prolog.ssh)
     Help is needed on this sheet.

 -- Style Sheet: Promela (promela.ssh)
     There is no way for this program to highlight send and receive primitives.

 -- Style Sheet: Python (python.ssh)
     Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python's elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

     The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the http://www.python.org,Python web site, and can be freely distributed.

     The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation.

     The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). Python is also suitable as an extension language for customizable applications.

 -- Style Sheet: Sather (sather.ssh)
     Sather is an object oriented language designed to be simple, efficient, safe, flexible and non-proprietary. One way of placing it in the `space of languages' is to say that it aims to be as efficient as C, C++, or Fortran, as elegant as and safer than Eiffel, and support higher-order functions and iteration abstraction as well as Common Lisp, CLU or Scheme.

     Implementation of the sheet based on the http://www.icsi.berkeley.edu/~sather/index.html,Sather home page.

     Heavy highlighting uses symbols for common mathematical operators.

     Written by  Larry W. Virden. Since everything, or almost, is a string, what is printed is not always what you would like.

 -- Style Sheet: Unified Diff (udiff.ssh)
     This style is meant to be used onto the output unidiffs, that is to say output from diff -u.

     Typical use of this style is:

          diff -u old new | a2ps -Eudiff

     The prologue diff helps to highlight the differences (a2ps -Ewdiff --prologue=diff).

 -- Style Sheet: Unity (unity.ssh)
