| # A note about this ebuild: this ebuild is Unified Build enabled but |
| # not in the way in which most other ebuilds with Unified Build |
| # knowledge are: the primary use for this ebuild is for engineer-local |
| # work or firmware builder work. In both cases, the build might be |
| # happening on a branch in which only one of many of the models are |
| # available to build. The logic in this ebuild succeeds so long as one |
| # of the many models successfully builds. |
