/trunk

A couple of miscellaneous accumulated fixes:

Fine-tune handling for dependency checking; provide some extra feedback on what packages to install, and try harder to detect virtual-package-vs-real-package.
Drop an obsolete macro from the macro expander. Obsolete at least so far as "it doesn't exist any more in CentOS 5"

[22]	1865	=head1 NAME
	1866
[140]	1867	debbuild - Build Debian-compatible .deb packages from RPM .spec files
[22]	1868
	1869	=head1 SYNOPSIS
	1870
	1871	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
	1872
[174]	1873	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2\|xz}
[22]	1874
[55]	1875	debbuild --rebuild file.{src.rpm\|sdeb}
[22]	1876
[89]	1877	debbuild --showpkgs
	1878
[22]	1879	=head1 DESCRIPTION
	1880
[140]	1881	debbuild attempts to build Debian-friendly semi-native packages from RPM spec files,
[55]	1882	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
	1883	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
[140]	1884	modules should be handled via CPAN+dh-make-perl instead as it's simpler than even tweaking
	1885	a .spec template.
[22]	1886
[55]	1887	As far as possible, the command-line options are identical to those from rpmbuild, although
[57]	1888	several rpmbuild options are not supported:
[22]	1889
[57]	1890	--recompile
	1891	--showrc
	1892	--buildroot
	1893	--clean
	1894	--nobuild
	1895	--rmsource
	1896	--rmspec
	1897	--sign
	1898	--target
	1899
	1900	Some of these could probably be trivially added. Feel free to send me a patch. ;)
	1901
	1902	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
	1903	you'll have to make heavy modifications anyway.
	1904
	1905	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
	1906	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
	1907
[55]	1908	=head1 ASSUMPTIONS
	1909
	1910	As with rpmbuild, debbuild makes some assumptions about your system.
	1911
	1912	=over 4
	1913
	1914	=item *
	1915
	1916	Either you have rights to do as you please under /usr/src/debian, or you have created a file
	1917	~/.debmacros containing a suitable %_topdir definition.
	1918
[57]	1919	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
	1920	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
	1921	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
[55]	1922	some subdirectories are created automatically as needed, but most are not.
	1923
	1924	=item *
	1925
	1926	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
	1927	executing shell scripts for much of their functionality. By default, debbuild also creates
	1928	install trees under /var/tmp - however this is (almost) entirely under the control of the
	1929	package's .spec file.
	1930
	1931	=item *
	1932
	1933	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
	1934	match, or be suitably symlinked one direction or another so that both programs are effectively
	1935	working in the same tree. (Or you could just manually wrestle files around your system.)
	1936
	1937	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
	1938	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
	1939	%_topdir macro definition, although there are many more things that rpmbuild can use from
	1940	~/.rpmmacros.
	1941
	1942	=back
	1943
[89]	1944	=head1 ERRATA
	1945
	1946	debbuild deliberately does a few things differently from rpm.
	1947
	1948	=head2 BuildArch or BuildArchitecture
	1949
	1950	rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
	1951	that for all packages. Debian's repository system is fairly heavily designed around the
	1952	assumption that a single source package may generate small binary (executable) packages
	1953	for each arch, and large binary arch-all packages containing shared data.
	1954
	1955	debbuild allows this by using the architecture specified by (in order of preference):
	1956
	1957	=over 4
	1958
	1959	=item * Host architecture
	1960
	1961	=item * BuildArch specified in .spec file preamble
	1962
	1963	=item * "Last specified" BuildArch for packages with several subpackages
	1964
	1965	=item * BuildArch specified in the %package section for that subpackage
	1966
	1967	=back
	1968
	1969	=head2 Finding out what packages should be built (--showpkgs)
	1970
	1971	rpmbuild does not include any convenient method I know of to list the packages a spec file
	1972	will produce. Since I needed this ability for another tool, I added it.
	1973
	1974	It requires the .spec file for the package, and produces a list of full package filenames
	1975	(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
	1976	This includes the .sdeb source package.
	1977
[57]	1978	=head1 AUTHOR
[55]	1979
[57]	1980	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
	1981	current is available at http://www.deepnet.cx/debbuild/.
[55]	1982
	1983	=head1 BUGS
	1984
[57]	1985	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
	1986	fixing this.
[55]	1987
[57]	1988	Many macro expansions are unsupported or incompletely supported.
	1989
	1990	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
	1991	environment variables and preprocessing that I haven't needed (yet).
	1992
	1993	Dcumentation, such as it is, will likely remain perpetually out of date.
	1994
	1995	%_topdir and the five "working" directories under %_topdir could arguably be created by
	1996	debbuild. However, rpmbuild doesn't create these directories either.
	1997
	1998	=head1 SEE ALSO
	1999
