=head1 NAME

pom2 - convert POD to Text, HTML, etc., with Pod::POM

=head1 SYNOPSIS

    pom2 text MyFile.pm > MyFile.txt
    pom2 html MyFile.pm > MyFile.html
    pom2 pod  MyFile.pm > Myfile.pod

    pom2 format [options] MyFile.pm > Myfile.xyz

=head1 DESCRIPTION

This script uses C<Pod::POM> to convert a Pod document into text,
HTML, back into Pod (e.g. to normalise a document to fix any 
markup errors), or any other format for which you have a view
module.

If the viewer is not one of the viewers bundled with C<Pod::POM>, the script
searches for an installed C<Pod::POM::View> module that matches the
specified format.  For example if you have C<Pod::POM::View::DocBook>
installed then you could say:

    pod2 docbook MyFile.pm > MyFile.xml

If any options other than C<--help> are specified then they are passed
to the constructor method of the view class.  For example:

    pod2 docbook --root=chapter --titlecasing MyFile.pm > MyFile.xml

would convert the Pod document to a DocBook chapter document with the
titlecasing option enabled.  Note that any string prefixed by "C<-->" is
taken as a valid option and passed to the constructor; if no value is
specified then a value of 1 is passed in.
