Cool, Edi Weitz's Regex Coach program (that I mentioned here before) made it into NTK.
THE REGEX COACH is a utility for Windows and Linux for testing out and walking through Perl-style regular expressions. You can interactively try out regexs on test data, find out which bits of the expression match what, view a graphical version parse tree, and get a confusing rendition of what the expression does in convoluted english. It's a minor miracle for anyone learning regular expressions, and will be a frequent timesaver even for those who have slashes on each side of their brain. And, of course, it's written in Common Lisp. What *is* it with everyone taunting the Perl guys these days?

I lived without C-h invoking help in emacs for years. Then I started using windowed emacs, where it works painlessly, and got attached to it. It took a while, but I finally figured out how to get it working from a gnome-terminal to a remote host running screen. This is very gnome and RedHat specific.
  1. On the local host, tell gnome-terminal "Swap Backspace/Delete"
  2. On the remote host, comment out bindkey -d -k kb stuff "\010" in /etc/screenrc
  3. On the remote host, add (normal-erase-is-backspace-mode 0) to ~/.emacs (and remove anything else backspace-related)

Works well so far. I have the feeling that as soon as I upgrade any of the pieces involved, it will stop working.
