-=head1 NAME
-
-Pod::Html - module to convert pod files to HTML
-
-=head1 SYNOPSIS
-
- use Pod::Html;
- pod2html([options]);
-
-=head1 DESCRIPTION
-
-Converts files from pod format (see L<perlpod>) to HTML format. It
-can automatically generate indexes and cross-references, and it keeps
-a cache of things it knows how to cross-reference.
-
-=head1 ARGUMENTS
-
-Pod::Html takes the following arguments:
-
-=over 4
-
-=item help
-
- --help
-
-Displays the usage message.
-
-=item htmlroot
-
- --htmlroot=name
-
-Sets the base URL for the HTML files. When cross-references are made,
-the HTML root is prepended to the URL.
-
-=item infile
-
- --infile=name
-
-Specify the pod file to convert. Input is taken from STDIN if no
-infile is specified.
-
-=item outfile
-
- --outfile=name
-
-Specify the HTML file to create. Output goes to STDOUT if no outfile
-is specified.
-
-=item podroot
-
- --podroot=name
-
-Specify the base directory for finding library pods.
-
-=item podpath
-
- --podpath=name:...:name
-
-Specify which subdirectories of the podroot contain pod files whose
-HTML converted forms can be linked-to in cross-references.
-
-=item libpods
-
- --libpods=name:...:name
-
-List of page names (eg, "perlfunc") which contain linkable C<=item>s.
-
-=item netscape
-
- --netscape
-
-Use Netscape HTML directives when applicable.
-
-=item nonetscape
-
- --nonetscape
-
-Do not use Netscape HTML directives (default).
-
-=item index
-
- --index
-
-Generate an index at the top of the HTML file (default behaviour).
-
-=item noindex
-
- --noindex
-
-Do not generate an index at the top of the HTML file.
-
-
-=item recurse
-
- --recurse
-
-Recurse into subdirectories specified in podpath (default behaviour).
-
-=item norecurse
-
- --norecurse
-
-Do not recurse into subdirectories specified in podpath.
-
-=item title
-
- --title=title
-
-Specify the title of the resulting HTML file.
-
-=item verbose
-
- --verbose
-
-Display progress messages.
-
-=back
-
