   3 # This is the open-adventure dungeon text coverage report generator. It
   4 # consumes a YAML description of the dungeon and determines whether the
   5 # various strings contained are present within the test check files.
   6 #
   7 # The default HTML output is appropriate for use with Gitlab CI.
   8 # You can override it with a command-line argument.
