LW confirmed that one prof-specific course description per course was typically sufficient, and that providing for a default course description and then an alternate one for use in the summer if necessary would be sufficient.
Based on that, we'll probably structure the site like this:
professors
profA
details
bio.inc
image.jpg
course100
coursedescription.inc
coursehandout.pdf
Then modify as needed the code that grabs snippets from within that structure for inclusion on e.g. courses offered page, prof details page.
