+'''
+FreeCAD IFC parser, by Yorik van Havre, based on work by Marijn van Aerle
+
+Usage:
+        import ifcReader
+        ifcdoc = ifcReader.IfcDocument("path/to/file.ifc")
+        print ifcdoc.Entities
+        myent = ifcdoc.Entities[20] # returns one entity
+        myent = ifcdoc.getEnt(20) # alternative way
+        polylines = ifcdoc.getEnt("IFCPOLYLINE") # returns a list
+        print myent.attributes
+
+The ifc document contains a list of entities, that can be retrieved
+by iterating the list (indices corresponds to the entities ids)
+or by using the getEnt() method. All entities have id, type
+and attributes. Attributes can have values such as text or number,
+or a link to another entity.
+
+Important note:
+
+1) For this reader to function, you need an IFC Schema Express file (.exp)
+available here:
+http://www.steptools.com/support/stdev_docs/express/ifc2x3/ifc2x3_tc1.exp
+For licensing reasons we are not allowed to ship that file with FreeCAD.
+Just place the .exp file together with this script.
+
+2) IFC files can have ordered content (ordered list, no entity number missing)
+or be much messier (entity numbers missing, etc). The performance of the reader
+will be drastically different.
