Implement a new @live-ebuilds which is generated from installed packages
that inherit from know live eclasses such as cvs, darcs, git, mercurial, and subversion. The list of eclasses is controlled by an "inherits" attribute that is configure in sets.conf for and instance of InheritSet. This set serves a purpose similar to the -scm ebuild suffix that has been proposed in GLEP 54. svn path=/main/trunk/; revision=11292
