1244	=head1 NAME
1245
1246	debbuild - Build Debian-compatible packages from RPM spec files
1247
1248	=head1 SYNOPSIS
1249
1250	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
1251
1252	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
1253
1254	debbuild --rebuild file.{src.rpm\|sdeb}
1255
1256	=head1 DESCRIPTION
1257
1258	This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1259	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1260	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1261	modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1262	things do not lend themselves to automated conversion.
1263
1264	As far as possible, the command-line options are identical to those from rpmbuild, although
1265	several rpmbuild options are not supported:
1266
1267	--recompile
1268	--showrc
1269	--buildroot
1270	--clean
1271	--nobuild
1272	--rmsource
1273	--rmspec
1274	--sign
1275	--target
1276
1277	Some of these could probably be trivially added. Feel free to send me a patch. ;)
1278
1279	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1280	you'll have to make heavy modifications anyway.
1281
1282	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1283	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1284
1285	=head1 ASSUMPTIONS
1286
1287	As with rpmbuild, debbuild makes some assumptions about your system.
1288
1289	=over 4
1290
1291	=item *
1292
1293	Either you have rights to do as you please under /usr/src/debian, or you have created a file
1294	~/.debmacros containing a suitable %_topdir definition.
1295
1296	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1297	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1298	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1299	some subdirectories are created automatically as needed, but most are not.
1300
1301	=item *
1302
1303	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1304	executing shell scripts for much of their functionality. By default, debbuild also creates
1305	install trees under /var/tmp - however this is (almost) entirely under the control of the
1306	package's .spec file.
1307
1308	=item *
1309
1310	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1311	match, or be suitably symlinked one direction or another so that both programs are effectively
1312	working in the same tree. (Or you could just manually wrestle files around your system.)
1313
1314	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1315	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1316	%_topdir macro definition, although there are many more things that rpmbuild can use from
1317	~/.rpmmacros.
1318
1319	=back
1320
1321	=head1 AUTHOR
1322
1323	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1324	current is available at http://www.deepnet.cx/debbuild/.
1325
1326	=head1 BUGS
1327
1328	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1329	fixing this.
1330
1331	Many macro expansions are unsupported or incompletely supported.
1332
1333	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1334	environment variables and preprocessing that I haven't needed (yet).
1335
1336	Dcumentation, such as it is, will likely remain perpetually out of date.
1337
1338	%_topdir and the five "working" directories under %_topdir could arguably be created by
1339	debbuild. However, rpmbuild doesn't create these directories either.
1340
1341	=head1 SEE ALSO
1342
1343	rpm(8), rpmbuild(8), and pretty much any document describing how to write a .spec file.
