1302	=head1 NAME
1303
1304	debbuild - Build Debian-compatible packages from RPM spec files
1305
1306	=head1 SYNOPSIS
1307
1308	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
1309
1310	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
1311
1312	debbuild --rebuild file.{src.rpm\|sdeb}
1313
1314	=head1 DESCRIPTION
1315
1316	This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1317	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1318	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1319	modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1320	things do not lend themselves to automated conversion.
1321
1322	As far as possible, the command-line options are identical to those from rpmbuild, although
1323	several rpmbuild options are not supported:
1324
1325	--recompile
1326	--showrc
1327	--buildroot
1328	--clean
1329	--nobuild
1330	--rmsource
1331	--rmspec
1332	--sign
1333	--target
1334
1335	Some of these could probably be trivially added. Feel free to send me a patch. ;)
1336
1337	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1338	you'll have to make heavy modifications anyway.
1339
1340	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1341	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1342
1343	=head1 ASSUMPTIONS
1344
1345	As with rpmbuild, debbuild makes some assumptions about your system.
1346
1347	=over 4
1348
1349	=item *
1350
1351	Either you have rights to do as you please under /usr/src/debian, or you have created a file
1352	~/.debmacros containing a suitable %_topdir definition.
1353
1354	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1355	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1356	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1357	some subdirectories are created automatically as needed, but most are not.
1358
1359	=item *
1360
1361	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1362	executing shell scripts for much of their functionality. By default, debbuild also creates
1363	install trees under /var/tmp - however this is (almost) entirely under the control of the
1364	package's .spec file.
1365
1366	=item *
1367
1368	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1369	match, or be suitably symlinked one direction or another so that both programs are effectively
1370	working in the same tree. (Or you could just manually wrestle files around your system.)
1371
1372	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1373	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1374	%_topdir macro definition, although there are many more things that rpmbuild can use from
1375	~/.rpmmacros.
1376
1377	=back
1378
1379	=head1 AUTHOR
1380
1381	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1382	current is available at http://www.deepnet.cx/debbuild/.
1383
1384	=head1 BUGS
1385
1386	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1387	fixing this.
1388
1389	Many macro expansions are unsupported or incompletely supported.
1390
1391	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1392	environment variables and preprocessing that I haven't needed (yet).
1393
1394	Dcumentation, such as it is, will likely remain perpetually out of date.
1395
1396	%_topdir and the five "working" directories under %_topdir could arguably be created by
1397	debbuild. However, rpmbuild doesn't create these directories either.
1398
1399	=head1 SEE ALSO
1400
1401	rpm(8), rpmbuild(8), and pretty much any document describing how to write a .spec file.
