35: lonparmset - Handler to set parameters for assessments and course
36:
37: =head1 SYNOPSIS
38:
39: lonparmset provides an interface to setting content parameters in a
40: course.
41:
42: It contains all the code for the "Content and Problem Settings" UI, except
43: for the helpers parameter.helper and resettimes.helper, and lonhelper.pm,
44: and lonblockingmenu.pm.
45:
46: =head1 DESCRIPTION
47:
48: This module sets coursewide and assessment parameters.
