"""Support for dynamic COM client support.

Introduction
 Dynamic COM client support is the ability to use a COM server without
 prior knowledge of the server.  This can be used to talk to almost all
 COM servers, including much of MS Office.

 In general, you should not use this module directly - see below.

Example
 >>> import win32com.client
 >>> xl = win32com.client.Dispatch("Excel.Application")
 # The line above invokes the functionality of this class.
 # xl is now an object we can use to talk to Excel.
 >>> xl.Visible = 1 # The Excel window becomes visible.
