Hi all! We would like to introduce a new ebuild variable named EBUILD_FORMAT, that tags the ebuild with a specific ebuild API version it provides or uses. ebuilds will get an automatic dependency on a version of portage that is required for the used API to work correctly. The mapping between API and portage versions will be distributed with our portage tree.
There are some major ebuild API changes being discussed. These changes need backward compatibility and the information from EBUILD_FORMAT can be used to provide backward compatiblity in an easy way. It can be used for the src_configure[1] support and it might as well be used to get backward compatibility for the RDEPEND=DEPEND[2] changes.
