Implement a new @live-ebuilds which is generated from installed packages |
| 10 |
that inherit from know live eclasses such as cvs, darcs, git, mercurial, |
| 11 |
and subversion. The list of eclasses is controlled by an "inherits" |
| 12 |
attribute that is configure in sets.conf for and instance of InheritSet. |
| 13 |
This set serves a purpose similar to the -scm ebuild suffix that has |
| 14 |
been proposed in GLEP 54. |
