927	debbuild - Build Debian-compatible packages from RPM spec files
928
929	=head1 SYNOPSIS
930
931	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
932
933	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
934
935	debbuild --rebuild file.src.{rpm\|deb}
936
937	=head1 DESCRIPTION
938
939	This script attempts to build Debian-friendly semi-native packages
940	from RPM spec files, RPM-friendly tarballs, and RPM source packages
941	(.src.rpm). It accepts I<most> of the options rpmbuild does, and
942	should be able to interpret most spec files usefully. Perl modules
943	should be handled via CPAN+dh-make-perl instead; Debian's conventions
944	for such things do not lend themselves to automated conversion.
945
946	As far as possible, the command-line options are identical to those
947	from rpmbuild, although several rpmbuild options are not supported.
