| # The purpose of this little shell script is to generate a settings.xml |
| # for Maven that contains a list of packages (as activated profiles) based |
| # on the last commit to Git. The idea is that this helps to reduce the |
| # number of CPU cycles that are required in a Gerrit verification build job |
| # by building only the relevant packages. |
| # (Relevant == the packages that are potentially affected by this change) |
