13\ingroup Geometry_classes
14
15Regions are groups of volumes having a common set of user tracking cuts.
16
17Class wrapper for regions used by Monte Carlo packages
18A region is composed by a list of logical volumes and defines a set
19of cuts. Used mainly to transport region information stored in
20GDML format to the clients requiring it from the transient geometry.
