In a fit of command line joy, I went about installing some programs. I tried to install the 'say' command (like Darwin has), and installed whatever program Ubuntu recommended -- unfortunately, without writing it down.

It ended up not being the right one, and I'm pretty sure I downloaded GNUStep -- there's not a folder in my home directory, and if I delete it and run 'say' again, it recreates and creates an 'installed-software.txt' file.

How do I uninstall GNUstep, and stop this from happening?
