* Project:      Text Counter
*
* Task Domains: MS-DOS
*
* Functional
* Description:  This file is designed to run from DOS to count how many
*               times a piece of text occurs.  This is useful for taking
*               source safe reports and counting lines added "Ins:",
*               deleted "Del:", or modified "To:".
