Course Import Plugin - Enroll (existing) users in a course and optionally create groups

This course import plugin allows you to import user enrollments from a delimited text file. New user accounts will not be created, so each of the users listed in the input file must already have an account set up in the site.

If a group name is include with any user record (line) then that user will be added to that group if it exists. You can optionally create new groups if they do not already exist.

This plugin is a refactor of the mass_enroll course admin mod done by Patrick Pollet and Valery Fremaux, using the existing groups import plugin (jamiesensei & tjhunt ?) as a template.

From the INSTALL.txt file:

Place the userenrols directory in the Moodle site's /course/import directory.

In order for the localization (interface strings and help buttons) to work, a small change must be made to the lib/moodlelib.php file (many apologies), in the places_to_search_for_lang_strings() function, at or about line 5296.
