- """Manages a dictionary of CLSID strings to Python classes.
- Primary use of this module is to allow modules generated by
- makepy.py to share classes. @makepy@ automatically generates code
- which interacts with this module. You should never need to reference
- this module directly.
- This module only provides support for modules which have been previously
- been imported. The gencache module provides some support for loading modules
- on demand - once done, this module supports it...
- As an example, the MSACCESS.TLB type library makes reference to the
- CLSID of the Database object, as defined in DAO3032.DLL. This
- allows code using the MSAccess wrapper to natively use Databases.
- This obviously applies to all cooperating objects, not just DAO and
- Access.
