1288	=head1 NAME
1289
1290	debbuild - Build Debian-compatible packages from RPM spec files
1291
1292	=head1 SYNOPSIS
1293
1294	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
1295
1296	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
1297
1298	debbuild --rebuild file.{src.rpm\|sdeb}
1299
1300	=head1 DESCRIPTION
1301
1302	This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1303	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1304	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1305	modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1306	things do not lend themselves to automated conversion.
1307
1308	As far as possible, the command-line options are identical to those from rpmbuild, although
1309	several rpmbuild options are not supported:
1310
1311	--recompile
1312	--showrc
1313	--buildroot
1314	--clean
1315	--nobuild
1316	--rmsource
1317	--rmspec
1318	--sign
1319	--target
1320
1321	Some of these could probably be trivially added. Feel free to send me a patch. ;)
1322
1323	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1324	you'll have to make heavy modifications anyway.
1325
1326	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1327	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1328
1329	=head1 ASSUMPTIONS
1330
1331	As with rpmbuild, debbuild makes some assumptions about your system.
1332
1333	=over 4
1334
1335	=item *
1336
1337	Either you have rights to do as you please under /usr/src/debian, or you have created a file
1338	~/.debmacros containing a suitable %_topdir definition.
1339
1340	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1341	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1342	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1343	some subdirectories are created automatically as needed, but most are not.
1344
1345	=item *
1346
1347	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1348	executing shell scripts for much of their functionality. By default, debbuild also creates
1349	install trees under /var/tmp - however this is (almost) entirely under the control of the
1350	package's .spec file.
1351
1352	=item *
1353
1354	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1355	match, or be suitably symlinked one direction or another so that both programs are effectively
1356	working in the same tree. (Or you could just manually wrestle files around your system.)
1357
1358	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1359	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1360	%_topdir macro definition, although there are many more things that rpmbuild can use from
1361	~/.rpmmacros.
1362
1363	=back
1364
1365	=head1 AUTHOR
1366
1367	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1368	current is available at http://www.deepnet.cx/debbuild/.
1369
1370	=head1 BUGS
1371
1372	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1373	fixing this.
1374
1375	Many macro expansions are unsupported or incompletely supported.
1376
1377	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1378	environment variables and preprocessing that I haven't needed (yet).
1379
1380	Dcumentation, such as it is, will likely remain perpetually out of date.
1381
1382	%_topdir and the five "working" directories under %_topdir could arguably be created by
1383	debbuild. However, rpmbuild doesn't create these directories either.
1384
1385	=head1 SEE ALSO
1386
1387	rpm(8), rpmbuild(8), and pretty much any document describing how to write a .spec file.
