+This is the open-adventure dungeon text coverage report generator. It
+consumes a YAML description of the dungeon and determines whether the
+various strings contained are present within the test check files.
+
+The default HTML output is appropriate for use with Gitlab CI.
+You can override it with a command-line argument.
+
+The DANGLING lists are for actions and messages that should be
+considered always found even if the checkfile search doesn't find them.
+Typically this will because an action emit a templated message that
+can't be regression-tested by equality.
