       Pod::Html::Util - helper functions for Pod-Html

SUBROUTINES

       Note: While these functions are importable on request from Pod::Html::Util, they are
       specifically intended for use within (a) the Pod-Html distribution (modules and test
       programs) shipped as part of the Perl 5 core and (b) other parts of the core such as the
       installhtml program.  These functions may be modified or relocated within the core
       distribution -- or removed entirely therefrom -- as the core's needs evolve.  Hence, you
       should not rely on these functions in situations other than those just described.

   "process_command_line()"
       Process command-line switches (options).  Returns a reference to a hash.  Will provide
       usage message if "--help" switch is present or if parameters are invalid.

       Calling this subroutine may modify @ARGV.

   "usage()"
       Display customary Pod::Html usage information on STDERR.

   "unixify()"
       Ensure that Pod::Html's internals and tests handle paths consistently across Unix, Windows
       and VMS.

   "relativize_url()"
       Convert an absolute URL to one relative to a base URL.  Assumes both end in a filename.

   "html_escape()"
       Make text safe for HTML.

   "htmlify()"
           htmlify($heading);

       Converts a pod section specification to a suitable section specification for HTML. Note
       that we keep spaces and special characters except "", ?" (Netscape problem) and the hyphen
       (writer's problem...).

   "anchorify()"
           anchorify(@heading);

       Similar to "htmlify()", but turns non-alphanumerics into underscores.  Note that
       "anchorify()" is not exported by default.

   "trim_leading_whitespace()"
       Remove any level of indentation (spaces or tabs) from each code block consistently.
