Remove g_irepository_register_file in favor of g_irepository_require.
2008-08-20 Colin Walters <walters@verbum.org> * girepository/girepository.c: Remove g_irepository_register_file in favor of g_irepository_require. There are two possible deployment scenarios for typelibs: First, separate in $DATADIR/gitypelibs/. Second, they may be embedded in shlibs. However since the first is now the normal case, the API is optimized around it. Refactor internals to look up typelibs for namespaces just-in-time, but we expect consumers to call g_irepository_require. Also, add some docs. No one has died from that before. * gir/Makefile.am: Need --library for glib. * giscanner/girwriter.py: Write out shared-library. * tools/g-ir-writer: Take the first --library argument as the target of shared-library. In the future we should make this nicer with pkg-config probably. svn path=/trunk/; revision=426
