Schedule Rules module (SRules) offer a set of tools used to define and manipulate scheduled elements, based on date Intervals (like meetings events, etc..)
SRules stores an ordered list of sessions which will be processed in that order to generate an occurence list. It can handle 'add' and 'exclude' sessions.
Each session is a set of rules ('normal rules') which indicates periods of time. This rules can include 'exclude' rules (in rrule terms) if they are intended to describe the 'normal' session.
