I raised the possibility of breaking up the files before and Travis was
agreeable to the idea. It is still in the back of my mind but I haven't got
around to doing anything about it. Maybe we should put together a step by
step approach, agree on some file names for the new files, fix the build so
it loads in the new stub files in the correct order, and then start moving
stuff. My own original desire was to break out the keyword parsers into a
separate file but I think Travis had different priorities.
