/trunk

First iteration of build-deps and install reqs:

Build requirements are checked, including version requirements.
Specified "Requires" will be listed in the Depends field in the package's control file; subpackage Requires should be added the same way. Versioned Require:'s are NOT (yet) supported.
Automatic shlibs requirements are partially processed - package names are added to the list, but versions are NOT. (dpkg's tool dpkg-shlibdeps seems to generate versions on *some* libs, but not all, without any immediately obvious pattern.)
Provides are passed through as-is.

Requires:/Depends: and Provides: versioning are not supported because
of the format used for dpkg to specify versions.

Debian does not support dependencies on library sonames, just the containing package name
or a virtual package. :/ Any package providing a soname I want to depend on will have to
Provide: something suitable.

1088	debbuild - Build Debian-compatible packages from RPM spec files
1089
1090	=head1 SYNOPSIS
1091
1092	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
1093
1094	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
1095
1096	debbuild --rebuild file.src.{rpm\|deb}
1097
1098	=head1 DESCRIPTION
1099
1100	This script attempts to build Debian-friendly semi-native packages
1101	from RPM spec files, RPM-friendly tarballs, and RPM source packages
1102	(.src.rpm). It accepts I<most> of the options rpmbuild does, and
1103	should be able to interpret most spec files usefully. Perl modules
1104	should be handled via CPAN+dh-make-perl instead; Debian's conventions
1105	for such things do not lend themselves to automated conversion.
1106
1107	As far as possible, the command-line options are identical to those
1108	from rpmbuild, although several rpmbuild options are not supported.
