=head1 INTRODUCTION |
|
|
|
This module provides subroutines which interact with the |
|
lonc/lond (TCP) network layer of LON-CAPA. And Can be used to ask about |
|
- classes |
|
- users |
|
- resources |
|
|
|
For many of these objects you can also use this to store data about |
|
them or modify them in various ways. |
|
|
|
This is part of the LearningOnline Network with CAPA project |
|
described at http://www.lon-capa.org. |
