- Retrieve information about groups in a course,
- Input:
-. Reference to hash to populate with group information.
-. Optional course domain
-. Optional course number
-. Optional group name
- Course domain and number will be taken from user's
- environment if not supplied. Optional group name will'
- be passed to lonnet::get_coursegroups() as a regexp to
- use in the call to the dump function.
- Output
- Returns number of groups in the course (subject to the
- optional group name filter).
- Side effects:
- Populates the referenced curr_groups hash, with key,
- value pairs. Keys are group names, corresponding values
- are scalars containing group information in XML. This
- can be sent to &get_group_settings() to be parsed.

- =item get_group_settings
- Uses TokeParser to extract group information from the
- XML used to describe course groups.
- Input:
- Scalar containing XML  - as retrieved from &coursegroups().
- Output:
- Hash containing group information as key=values for (a), and
- hash of hashes for (b)
- Keys (in two categories):
- (a) groupname, creator, creation, modified, startdate,enddate.
- Corresponding values are name of the group, creator of the group
- (username:domain), UNIX time for date group was created, and
- settings were last modified, and default start and end access
- times for group members.
- (b) functions returned in hash of hashes.
- Outer hash key is functions.
- Inner hash keys are chat,discussion,email,files,homepage,roster.
- Corresponding values are either on or off, depending on
- whether this type of functionality is available for the group.
