* The INTRODUCTION MICRO MODULE is used to insert and edit
|
|
* an introduction section on a Dokeos Module. It can be inserted on any
|
|
* Dokeos Module, provided a connection to a course Database is already active.
|
|
*
|
|
* The introduction content are stored on a table called "introduction"
|
|
* in the course Database. Each module introduction has an Id stored on
|
|
* the table. It is this id that can make correspondance to a specific module.
|

|
|
* 'introduction' table description
|
|
* id : int
|
|
* intro_text :text
