-  # Version mask is “X.X.XXXX-R” where “X.X.XXXX” is a mandatory version of Psi
-  # and “-R” ending is optional revision number.
-  #
-  # The “psi-plus-snapshots” generally provides snapshots of these separate
-  # repositories glued together (there are also dependencies/libraries):
-  #
-  # 1. Psi
-  # 2. Plugins pack for Psi
-  # 3. “psimedia” plugin
-  # 4. Resources for Psi (icons, skins, sounds)
-  #
-  # “X.X.XXXX” is literally a version of Psi.
-  # So often when for instance plugins are updated separately a new snapshot is
-  # created. And that snapshot would also be linked to “X.X.XXXX” version.
-  # So many commits may have the same associated version of the snapshot.
-  # But mind that only one Git tag is created for “X.X.XXXX” version.
-  #
-  # It’s not yet defined in the Psi+ project what value to use as a version for
-  # any further releases that don’t change Psi version.
-  #
-  # Let’s do what Debian does for instance (appends “-R” where “R” is a revision
-  # number).
-  # E.g. https://tracker.debian.org/news/1226321/psi-plus-14554-5-migrated-to-testing/
