36: =head1 SYNOPSIS
37:
38: Contains utilities used to determine the LON-CAPA version
39: requirement in a course, based on course type, parameters,
40: responsetypes, and communication blocking events.
41:
42: =head1 DESCRIPTION
43:
44: lonrelrequtilities.pm includes a main subroutine:
45: get_release_req() which will return the current major
46: version and minor version requirement (if it exists).
47:
48: =head1 SUBROUTINES
49:
50: =over
51:
52: =item &init_global_hashes()
53:
54: Initializes package hashes containing version requirements for
55: parameters, responsetypes, course types, anonsurvey
56: parameter, and randomizetry parameter.
57:
58: =item &get_release_req()
59:
60: Returns current major version and minor version requirements for a course,
61: based on: coursetype, parameters in use, responsetypes in use in course
62: content, and communication blocking features in use in blocks with end dates
63: in the future, or in blocks triggered by activation of a timer in a timed quiz.
