+When a model has its '_inherits' defined, the associated fields are always
+set to 'required'. These models cannot be imported in the web client 6.1
+because the web client insists that these fields be present in the import
+file. See https://bugs.launchpad.net/bugs/930318.
+
+This module makes the web client query the content of a model's
+'_inherits' so that it can exclude them from the required fields at import
+time.
+
+Due to the applied method of 'monkey patching', the installation of this
+module on one database will affect all databases on the same OpenERP
+installation.
+
+This bug does not affect OpenERP 7.0, in which the import function has
+been refactored.
