+	help
+	  In case a package use a git repository as source. Enabling this
+	  option will archive (shallowed) bare git repository instead of plain
+	  files. In order to distinguish these archives from classical ones,
+	  their names end with .git.tar.gz.
+
+	  Enable this option if you work with upstream and are interrested to
+	  have a better workflow with upstream team. Notice archive generation
+	  is about 25% slower and archives are 20 to 50% bigger. Time to extract
+	  archives are identical with or without this option.
