[python-win32] Python COM User Defined Types

You would write:

    # Create a new structure
    s = win32com.client.Record("StructName", object)

where 'object' is (any) COM object from the library you are using - eg, the
object with the WriteMsg2 method.

These constants are only available once the generated code for the COM
object has been imported.  This is generally done by one of the gencache
modules, or even by normal "Dispatch()", assuming makepy has been run
manually.  ie, the constants will only be available after the object has
been created.

Clever, eh? <wink>

Ignore them.  I should remove the generated comment.

Nope - like above.
