The "webcalendar 1.2" folder contains the latest production releases of
WebCalendar.
The "webcalendar-devel" folder contains development releases not intended
for use in production environments.
The "webcalendar-1.0" folder contains the out-dated WebCalendar 1.0.X releases,
which are no longer supported. Because of known exploits with 1.0.X, new
installs should ALWAYS be based on version 1.2.
