I never use those and don't really like them. I prefer completion to be
slow the first time I complete something than for it to be out-of-date.

Unfortunately, this doesn't work on the system I tried it on, using
Adobe's rpm. /usr/bin/acroread is a symbolic like to
/usr/local/Adobe/Acrobat7.0/bin/acroread. Handling that involves using ls
to get the symlink destination.

Is acroread always a script? The following works well (and very quickly)
on any system I have access to:
  grep '^ver=' =acroread
