completion scripts are very very useful, but writing them is a disorganized mess.

It would almost be easier to modify the bash source itself to read and use a regular grammar, say:

  foo [-p <pid>] [-f <configfile>]
  <pid>: {ps -eo pid}
  <configfile>: {ls -1 *.cfg}

or maybe something even nicer with help text
