34: refresh_courseids_db.pl
35:
36: =head1 SYNOPSIS
37:
38: refresh_courseids_db.pl is run on a library server and gathers
39: course information for each course for which the current server is
40: the home server. Entries (excluding last access time) for each course
41: in nohist_courseids.db are updated.
42:
43: =head1 DESCRIPTION
44:
45: refresh_courseids_db.pl will update course information, apart
46: from last access time, in nohist_courseids.db, using course data
47: from each course's environment.db file.
