Olivier,
Thanks for the reply. Your code below showed me
how to customize the indentation along with
the help facility.
However, according to the emacs help this should work:
(setq c-basic-offset 4)
but it doesn't -- it has absolutely no effect that I can tell.
If you understand why the above statement won't work I'd
like to know. But regardless thanks for the help.
