RE: IDE versus emacs

I recently discovered that CYGWIN delivers "Exuberant Ctags" (Yes, etags too.) 
and it is used instead of emacs' etags. (GPL, available at 
http://ctags.sourceforge.net.)

Exuberant Ctags can be extended to look for other things via regular 
expression. It is a wonderful thing!

I can now look for tags in my shell code to by running: 
    etags --langdef=shell --regex-shell='/function 
[_[:alnum:]]+/[_[:alnum:]]+/' --language-force=shell
(Unfortunate side-effect: That can also pick up comments, so I also have to fix 
things:
    sed -n -e '/#/d' -ep < TAGS > TTT && mv TTT TAGS
Oh, well.)
Shell programming is suddenly almost pleasant!
