1108	debbuild - Build Debian-compatible packages from RPM spec files
1109
1110	=head1 SYNOPSIS
1111
1112	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
1113
1114	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
1115
1116	debbuild --rebuild file.src.{rpm\|deb}
1117
1118	=head1 DESCRIPTION
1119
1120	This script attempts to build Debian-friendly semi-native packages
1121	from RPM spec files, RPM-friendly tarballs, and RPM source packages
1122	(.src.rpm). It accepts I<most> of the options rpmbuild does, and
1123	should be able to interpret most spec files usefully. Perl modules
1124	should be handled via CPAN+dh-make-perl instead; Debian's conventions
1125	for such things do not lend themselves to automated conversion.
1126
1127	As far as possible, the command-line options are identical to those
1128	from rpmbuild, although several rpmbuild options are not supported.
