	792	debbuild - Build Debian-compatible packages from RPM spec files
	793
	794	=head1 SYNOPSIS
	795
	796	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
	797
	798	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
	799
	800	debbuild --rebuild file.src.{rpm\|deb}
	801
	802	=head1 DESCRIPTION
	803
	804	This script attempts to build Debian-friendly semi-native packages
	805	from RPM spec files, RPM-friendly tarballs, and RPM source packages
	806	(.src.rpm). It accepts I<most> of the options rpmbuild does, and
	807	should be able to interpret most spec files usefully. Perl modules
	808	should be handled via CPAN+dh-make-perl instead; Debian's conventions
	809	for such things do not lend themselves to automated conversion.
	810
	811	As far as possible, the command-line options are identical to those
	812	from rpmbuild, although several rpmbuild options are not supported.
