  Documentation is available in various forms
  • Traditional manual pages (as pod) are enclosed in each package.
  • The HTML version of the manual pages is much more useful. They are available to browse directly.
  • Example scripts are also enclosed in some of the distributions. Have a look in the examples/ directories.
  All versions
  Mark's Perl modules use OODoc to be generated. That module extracts pseudo-POD from source files, and converts that into real POD and real HTML. The processed files are released on CPAN. The original files are only available from this website, as "raw" releases.
