Wizard is a Git-based autoinstall management system for scripts.
-Its commands are:
- stat Generate statistics about autoinstalls
+User commands:
+ backup Backup data not on filesystem (database, etc)
+ install Installs an application
+ migrate Migrate autoinstalls from old format to Git-based format
+ remove Removes an autoinstall, databases and other files
+ restore Restores files and database to previous version
+ upgrade Upgrades an autoinstall to the latest version
-See '%prog help COMMAND' for more information on a specific command.

-# migrate Migrate autoinstalls from old format to Git-based format
+Administrative commands:
+ blacklist Marks an autoinstall to not try upgrades
+ errors Lists all broken autoinstall metadata
+ list Lists autoinstalls, with optional filtering
+ mass-migrate Performs mass migration of autoinstalls of an application
+ mass-upgrade Performs mass upgrade of autoinstalls of an application
+ research Print statistics about a possible upgrade
+ summary Generate statistics (see help for subcommands)
+
+Utility commands:
+ prepare-pristine Downloads and extracts pristine upstream files
+ prepare-new Prepares a new repository
+ prepare-config Prepares configuration files for versioning
+ quota Prints the usage and available quota of a directory
