module RIM

# RIM revision status object.
#
# Revision status objects hold the RIM status of a specific project git revision.
# As a special case, this could also be the status of the current working copy.
#
# The revision status consists of a set of module status objects,
# one for each module known to RIM in that revision. 
# The module status points to a RimInfo object holding attribute values 
# valid for that specific revision as well as the current dirty state as
# calculated by DirtyCheck and the module directory.
#
# Revsion status objects can have parent status objects. This way,
# chains and even trees of status objects can be built. For example in
# case of a merge commit, the corresponding status object would have
# two parent status objects, one for each parent git commit.
#
