As reported by Elena in
The import groups feature (moved to Settings > Course administration > Users > Groups in 2.0) needs a help popup.
The string importgroups is currently in moodle.php. I suggest moving it to group.php.
Please could the following help and link strings be added:
$string['importgroups_help'] = 'Groups may be imported via text file. The format of the file should be as follows:
- Each line of the file contains one record
- Each record is a series of data separated by commas
- The first record contains a list of fieldnames defining the format of the rest of the file
- Required fieldname is groupname
- Optional fieldnames are description, enrolmentkey, picture, hidepicture';
$string['importgroups_link'] = 'group/import';
