Excellent!  Here's an updated patch incorporating your suggestions,
and also with the following additional changes:

* Arguments to install and remove are now optional, so --install a b
  works without the '='.

* I fixed a bug where "--upgrade gcc" (without the '=') would upgrade
  everything.

* I updated the manual to reflect the new syntax, by adding @dots{}
  in a few places with small changes to the text.

What do you think?
