script/undo_last_upgrade

   1 #!/usr/bin/env ruby

   3 # Convenience command to revert effects of the last run of
   4 # script/upgrade_to or script/upgrade_to_next_version.
   5 #
   6 # NOTE: only reverts to state before last upgrade. So if you upgrade
   7 # several versions in one go, reverting will only jump you back one
   8 # version, not to the original you started from.
