// vim:ts=8:sw=2:noet (VIM format settings)

Felix:

I noticed you have added this to most files in your own 
branches.

If you make a branch that differs from master only by the 
addition of this line, I will push it to master.

To everyone else:

This line tells VI how to format and indent the code.  It's not 
necessary for emacs, because the default in emacs is what gnucap 
uses.

It means:

Physical tab stop = 8.
(so it looks good when viewed with cat or less)

"shiftwidth" =2
how much each level is indented

noet
no expand tab
