	840	debbuild - Build Debian-compatible packages from RPM spec files
	841
	842	=head1 SYNOPSIS
	843
	844	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
	845
	846	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
	847
	848	debbuild --rebuild file.src.{rpm\|deb}
	849
	850	=head1 DESCRIPTION
	851
	852	This script attempts to build Debian-friendly semi-native packages
	853	from RPM spec files, RPM-friendly tarballs, and RPM source packages
	854	(.src.rpm). It accepts I<most> of the options rpmbuild does, and
	855	should be able to interpret most spec files usefully. Perl modules
	856	should be handled via CPAN+dh-make-perl instead; Debian's conventions
	857	for such things do not lend themselves to automated conversion.
	858
	859	As far as possible, the command-line options are identical to those
	860	from rpmbuild, although several rpmbuild options are not supported.
