This custom version is deprecated. Starting with versions 5.11.x (now there is available a snapshot for 5.11.0), there is a constraint teacher(s) min days per week, so no need for this custom version anymore.
FET variant for user mbarsan
Modification: constraint teachers min hours daily (mH) allows only one free day for teachers. This way, if you also constrain each teacher by max days per week=n_days_per_week-1, you'll get a timetable in which each teacher works n_days_per_week-1, with at least mH hours per day.
This is what user mbarsan requested.

(I prefer you to use this link, because I might update files and change their names. Please use the new 5_10_2 version. You have also here a directory with older versions named "old" - deprecated, NOT recommended).

Probably usable by some Italian school(s)?
12 August 2009: I updated from FET 5.10.2.
This custom version is now deprecated, not needed, because official FET 5.11.0 (there is now available a snapshot), has constraints teacher(s) min days per week.
