   6 # checks all the repositories and updates mirrored repositories and
   7 # repacks push-repositories when needed.

   9 # Execute with parameter --all-once to run only once (on all projects)
  10 # instead of in infinite loop. Or call with parameter --one and name
  11 # of a project (not full path, without .git suffix) to run maintenance
  12 # only on that particular project.
  13 #
  14 # Use -q as VERY FIRST parameter to enable quiet mode (use in cronjobs).
