#
# The data consists of blocks of lines for each course.  Each block of lines
# is separated by a line consisting of a single '0'.  The first line of each
# block gives title information.  The remaining lines are either descriptive
# or give time and location information.  The latter will have the department
# code beginning in column 24; the former will not.  Every line in a block
# will have the course number as its second word.  If the course number is
# 1, we're talking about departmental information, which is elided.
#
# There is a bunch of uninteresting information in blocks; this we remove.
#
# Following is a sample of a data file.
