First and foremost, I must state my apologies regarding my lack of CVS
updates. School will come to an end tomorrow, and then I am free to find a
decent internet connection for my development box.
- Ok. Remember, this is a really bad way to check if loadkeys actually
worked. I am not sure if you said "Yes, that's fine" to my execve(); (where
we can check loadkey's return value directly, much more accurate. Any sort
of error checking on system() is no error checking at all) or installation
idea. For tomorrow's CVS though, I will return that perror for you.
- How about we include the maps needed (by default configuration) by Akka
into the Akka package itself. It will surely make that poor excuse for
"default configuration" much more portable. I was thinking of writing an
autoconf tool, but it is needless if we just include the fonts/keymaps we
will be using.

I tend to agree with Samy here. I'm all for reducing library dependencies..
is, Akka has far too many dependencies for what it does. That's just my
it. I would be very much in favor of a 'light-weight' akka.

The 'programmer' also reads the doc++ output. Thought I would note that the
commenting is incomplete and inconsistent still. I would suggest adding the
comments, but maintainng the doc++ style (which I personally like) - it's
readable when viewing src, and very nice to output documentation later.
