NAME

podtree2html - translate a POD to HTML

SYNOPSIS

"podtree2html" ["--base" url] ["--css" url] ["--"["no"]"toc"] ["--hr" level] ["--bgcolor" #rrggbb] ["--text" #rrggbb] ["--variables" values.pl] source dest [template] [variable=value ...]]

DESCRIPTION

"podtree2html" reads the POD in file source, translates it to HTML, and writes it to file dest. dest is created world-readable.

If a template file is provided, then template will be filled in by the "Text::Template" module and written to dest. Here is a minimal template, showing all the variables that are set by "podtree2html".

  <html>
   <head>
    <base href="{$base}">
    <link href="{$css}" rel="stylesheet" type="text/css">
    <title>{$title}</title>
   </head>
   <body bgcolor="{$bgcolor}" text="{$text}">
    {$toc}
    {$body}
   </body>
  </html>

If the "--variables" option is provided, then the file values.pl will be executed with a "do" call before the template is filled in. values.pl may contain arbitrary Perl code. The program fragments in the template are evaulted in the "Pod::Tree::HTML" package. Any variables that values.pl sets in this package will be available to the template.

Additional scalar variables may be set on the command line with the variable=value syntax. Do not prefix variable with a "$" sigil. Variables set on the command line override variables set in values.pl.

OPTIONS
