+Clean your OpenERP database from remnants of modules, models, columns and
+tables left by uninstalled modules (prior to 7.0) or a homebrew database
+upgrade to a new major version of OpenERP.

+After installation of this module, go to the Settings menu -> Technical ->
+Database cleanup. Go through the modules, models, columns and tables
+entries under this menu (in that order) and find out if there is orphaned data
+in your database. You can either delete entries by line, or sweep all entries
+in one big step (if you are *really* confident).

+Caution! This module is potentially harmful and can *easily* destroy the
+integrity of your data. Do not use if you are not entirely comfortable
+with the technical details of the OpenERP data model of *all* the modules
+that have ever been installed on your database, and do not purge any module,
+model, column or table if you do not know exactly what you are doing.
