=head1 NAME

podlint - check POD for correctness using Pod::POM

=head1 SYNOPSIS

podlint MyFile.pm

=head1 DESCRIPTION

This script uses Pod::POM to parse a Pod document with full 
warnings enabled, effectively acting as a syntax and structure
checker.

The -f option can be specified to have the parsed Pod Object Model
printed to STDOUT with any markup errors fixed.  Note there are some
critical parse errors that can't be handled and fixed by the parser
and in this case the script will terminate reporting the error.
