A QnD fix to answer which files to process.

Currently reads from an arbitrary file in the current working directory.
This requires each project then to define said file. Of course, it
doesn't help you with keeping it up to date, so this is only a
short-term solution to make it immediately useful for non-C/C++-based
code... A longer term solution should use regexes and/or globs and warn
about unignored files. I digress...
