Subject: 	* Fixes for code generation. 	 - Generate make fragments in
 $(srcdir) to fix VPATH builds. 	 - rubygen: generates its own .mk
 fragment 	 - rubygen: moved template info from Makefile.am to generated
 rubygen.mk, fixes circular dependency between Makefile and rubygen.mk 	 -
 removed unused templates.
