Defect 1851 - modified lonprintout.pm to include course personnel in the
listing of 'students' This is an existing option for the <student> tag in
the helper. Seems to attempt to do what its' supposed to do most of what it
should do.. I need to investigate that access rights are appropriately handled
and other similar issues.
