Yeah... I read so much. Five years of pitch-black
computer science. What do I get? Not a dime in my
pocket and only "read the Emacs manual", "read the
Elisp manual", read that, read this... Do I go around
telling everyone: write code, write code, write
code...? No. But the only reason I don't do that is
because I know no one or very few would actually do it
if I did. Well, let's see if anyone comments on the
material in a more applied way... stayed tuned for the
next episode of Operation Emacs - the same channel, the
same terminal!
PS. But thanks again for you other comments that were
very helpful. DS.
