.SH DESCRIPTION
twversion formerly known as Version Tool, is a GUI tool for the SCCS command set.
It allows you to perform SCCS functions using an interactive GUI.
You can put files under SCCS control,
check in and check out files, and visually peruse
the history and contents of SCCS files at various points in the
file history.
You can also use twversion to execute Filemerge to compare
the differences between selected delta versions of a file. If you have more than 2000 files in a single directory under SCCS control using TeamWare, you could experience problems. Subdivide workspace directories for better performance. 
.LP
To start 
.B twversion, 
type
.B twversion
on the command line.
.SH ENVIRONMENT
.LP
You can set the following environment variable in conjunction with twversion.
