+timetable of a school, high-school or university.  It uses a fast and
+efficient timetabling algorithm.
+
+Usually, FET is able to solve a complicated timetable in maximum 5-20
+minutes.  For simpler timetables, it may take a shorter time, under
+5 minutes (in some cases, a matter of seconds).  For extremely
+difficult timetables, it may take a longer time, a matter of hours.")
