This directory holds a C course I'm in the process of writing.  At this
writing it's still definitely incomplete, but it's probably more than
half done - see course.txt for its current state.  It's complete enough
that I'm making it available for anyone who wants to look at it as it
is now.  Comments welcome.

Other files in ths directory are probably related, but not actually
part of the course per se.  They may or may not be worth looking at.
Any that I actually support will be mentioned here.
