+					courses the user is registered for
+==============================================================================
+	version info:
+	-------------
+	-> version 2.2 : Patrick Cool, patrick.cool@ugent.be, november 2004
+	Personal Agenda added. The user can add personal agenda items. The items
+	are stored in a dokeos_user database because it is not course or platform
+	based. A personal agenda view was also added. This lists all the personal
+	agenda items of that user.
+
+	-> version 2.1 : Patrick Cool, patrick.cool@ugent.be, , oktober 2004
+	This is the version that works with the Group based Agenda tool.
+
+	-> version 2.0 (alpha): Patrick Cool, patrick.cool@ugent.be, , oktober 2004
+	The 2.0 version introduces besides the month view also a week- and day view.
+	In the 2.5 (final) version it will be possible for the student to add his/her
+	own agenda items. The platform administrator can however decide if the students
+	are allowed to do this or not.
+	The alpha version only contains the three views. The personal agenda feature is
+	not yet completely finished. There are however already some parts of the code
+	for adding a personal agenda item present.
+	this code was not released in an official dokeos but was only used in the offical
+	server of the Ghent University where it underwent serious testing
+
+	-> version 1.5: Toon Van Hoecke, toon.vanhoecke@ugent.be, december 2003
+
+	-> version 1.0: Eric Remy, eremy@rmwc.edu, 6 Oct 2003
+	The tool was initially called master-calendar as it collects all the calendar
+	items of all the courses one is subscribed to. It was very soon integrated in
+	Dokeos as this was a really basic and very usefull tool.
