=head1 NAME
docbook2man-spec.pl - convert DocBook RefEntries to Unix manpages
=head1 SYNOPSIS
The sgmlspl script from the SGMLSpm Perl module must be used to run
this script. Use it like this:
nsgmls some-docbook-document.sgml | sgmlspl docbook2man-spec.pl
See man page or included DocBook documentation for details.
=head1 DESCRIPTION
This is a sgmlspl spec file that produces Unix-style
man pages from DocBook RefEntry markup.
