#	TEMPLATE FOR THE FRONT-END TO CC

# This shell script creates the front-end to the cc command.  It should be run
# in the same directory where the front-end to cc is going to reside.  The front-end
# to cc is a one line shell script which calls the executable cc command
# with the appropriate '-Y' options.  This shell script will be given the same
# name as the executable cc.  Therefore, the front-end to cc and the executable
# cc command can not exist in the same directory when using this shell script.
# A logical place to put the executable cc command is the same directory where
# other tools which are not called directly are placed (E.g., /lib).
