Subject: [PATCH] A new saner interface for parsing spec files - For now just a
 wrapper around parseSpec() that returns *gasp*   a pointer to a parsed spec
 structure. - Limit the amount of goo that needs passing - optimally we'd only
 need   the spec + parsing flags, but due to %{buildroot} macro abuse in specs
   we'll need that for now too.
