+
+ Convert source code (c,java,perl,html,...) into formatted html.
+
+=head1 SYNOPSIS
+
+  use Code2HTML;
+  $html = code2html( $sourcecode );
+  # or
+  code2html( infile        => 'file.java' , 
+             outfile       => 'file.html',

+             langmode      => 'perl' ,
+             # many other options
+           );
+
+=head1 DESCRIPTION
+
+Code2HTML converts source code into color-coded, formatted html,
+either as a simple code2html() function call, or as an Apache handler.
+
+This package is an adaptation of Peter Palfrader's code2html application.
+
+The statement 
+
+ use Code2HTML;
+
+exports the function code2html(), which takes the following arguments
+
+ $html = code2html(
+                        input           => $source_code,
+                        infile          => 'filename.extension',
+
+                        outfile         => 'file.html',
+                        outputformat    => 'html',      # or html-dark, or ...
+
+                        langmode        => 'java',      # or perl,html,c,...
+                        langfile        => 'langFile',  # specify alternative
+                                                        # syntax definitions
+
+                        linenumbers     => 1,           # turn on linenumbers
+                        linknumbers     => 1,           # linenumber links
+                        line_number_prefix => '-',      # linenumber anchors
+                        replacetabs     => 8,           # tabs to spaces 
+
+                        noheader        => '',          # don't use template
+                        template        => 'filename',  # override template
+
+                        title           => $title,      # set html page title
+                        content_type    => 1,           # output httpd header
+                  );
+
+All input parameters are optional except the source code 
+specification, which must be defined by either input or infile keys, or
+by passing exactly one argument which will then be taken to be the 
+source code.
+
+ input          source code to be converted (or set source -infile)
+
+ infile         name of file with code  to be converted (or use -input)
+
+ langmode       language of source file.  If omitted, code2html
+                will try to guess from the language from the file extension
+                or start of the source code.  Language modes provided are
+
+                        ada, ada95, awk, c, c++, cc, cxx, groff, html,
+                        java, javascript, js, m4, make, makefile, pas,
+                        pas, pascal, perl, plain, pov, povray, ruby, sql.
+
+ langfile       filename of file with alternative syntax definitions
+
+ outfile        name of file to put html in.  If omitted, 
+                just return html in $html=code2html(...)
+
+ outputformat   style of output html.  Available formats are 
+                html (default), html-dark, html-light, html-nobg.
+
+ replacetabs    replace tabs in source with given number of spaces
+
+ title          set title of output html page
+
+ content_type   output a Content-Type httpd header
+ linenumbers    print line numbers in source code listing
