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.
