| 5 | # @DESCRIPTION: |
| 6 | # Atoms mentioned in CONFLICT_LIST need to either be unmerged or upgraded |
| 7 | # prior to this package being installed, but we don't want to have an explicit |
| 8 | # dependency on that package. So instead, we do the following: |
| 9 | # 1. When we are installed, ensure that the old version is not installed. |
| 10 | # 2. If old version is installed, ask emerge to consider upgrading it. |
| 11 | # This consideration is listed as PDEPEND so that we don't add an |
| 12 | # explicit dependency on the other package. |
