"""Generic error lists.

Error lists are used to parse output in mozharness.base.log.OutputParser.

Each line of output is matched against each substring or regular expression
in the error list.  On a match, we determine the 'level' of that line,
whether IGNORE, DEBUG, INFO, WARNING, ERROR, CRITICAL, or FATAL.

TODO: Context lines (requires work on the OutputParser side)

TODO: We could also create classes that generate these, but with the
appropriate level (please don't die on any errors; please die on any
warning; etc.) or platform or language or whatever.
