My own experience is that parsing ps can be difficult if you want to be
portable and want more than basic information. Quite clearly, I could just
be dense, but if it helps, you can look at the configure.in in the CVS tree
at http://sourceforge.net/projects/netsaintplug (GPL, sorry. But if you
find anything worthwhile, and borrowing concepts results in similar code, I
won't complain).

I wouldn't be at all surprised if you found a better approach - my
configuration above, to my mind at least, is not pretty. I hope you do find
a better approach - I know I'll be peeking at your code to see.
