g-ir-inspect: Inspect GI typelibs
Various distributions (mainly RPM based so far) make use of automatic dependencies extracted from typelib files (they can require other typelibs and also shared libraries) Current features * Print used shared libraries * Print used typelib dependencies Based-on-patch-by: Dominique Leuenberger <dimstar@opensuse.org> Reference: https://bugzilla.gnome.org/show_bug.cgi?id=665672 Reviewed-by: Colin Walters <walters@verbum.org> Signed-off-by: Dominique Leuenberger <dimstar@opensuse.org> Signed-off-by: Igor Gnatenko <ignatenko@redhat.com>
