   9 # if a patch adds a source file, it is necessary to delete it afterwards and
  10 # remove all related build artifacts. It will also be necessary to rebuild the game
  11 # for testing the next patch, even if that new patch doesn't change the code.

  14 # handling a decent input of patches on Phabricator.

  17 # cleanup, and resorts to a clean checkout in case of failure.
