Yet another lyx guide

[robin]

In case anyone's interested, I've just written a very basic guide to
lyx, available at 

www.bilkent.edu.tr/~robin/lyxguide.pdf

It's aimed at university students and staff, so doesn't have anything
about letter class etc. - it's just something to get people started in
the right direction and give a brief taste of some of the things that
can be done with lyx.  Feedback welcome!
