#  Filename : easySCCS.sh
#  Creation Date : 01/09/2003
#  Author/Submitter : arjun.singh@hpsglobal.com
#  Function : A utility script for automation of SCCS unix utility. 
#    A menu based command for easy version control using 
#    SCCS commands. Gives a better control over commands.
#  Pre-requisite : 
#    1. Set the SCCSDIR in your environment. This will point to the directory 
#       location for sccs files.
#       e.g. export SCCSDIR=$HOME/SCCS   here SCCS is the directory for files. 
#    2. A link 'SCCS' must exit in your working dir, pointing to SCCS dir
#		    e.g. $HOME/<work_dir>/SCCS -> $HOME/SCCS
#    3. create a backup directory 'bak' in working directory e.g
#			$HOME/<work_dir>/bak
#
