NATO Science Series III: Computer \& Systems Sciences 196, 185-198 (2005). 2005 Amsterdam: IOS Press EN Summary: The aim of the article is to describe a new feature in the computer algebra package BERGMAN -- an interface shell that simplifies the usage of the system. We start from a brief description of BERGMAN and problems arising in its interface. Then we show how the shell solves those problems. At last we describe in more details how to use the shell and comment its additional possibilities and future development.
