This directory contains the lecture notes for CSC 252.  At the beginning
of the semester, most files will be left over from when I last taught the
course.  I'll update them over the course of the semester; check the
file modification dates and the top few lines of the file if you're unsure.

I provide these notes with some hesitation.  My concern is that they are
meant primarily for me to lecture from, not for students to read.
    I don't spell everything out clearly.
    I include notes to myself.
    I sometimes include material that I don't get around to talking about.
    I sometimes talk about things that aren't in the notes.
    I sometimes make mistakes in the notes that I correct on the fly in class.

At the same time
    Some of you can't help being absent from time to time.
    The notes emphasize the material that is likely to be on the exams.
    If you have some notes already you may be able to pay better attention
        in class.

Therefore,
PLEASE treat the notes as if they came with a typical free software
"unlicense":
    This stuff is made available in the hope that somebody will find it
    useful.  No guarantee is made, however, that it is good for anything
    in particular.  Use at your own risk.
