#	Compare ascii files
# CALLING SEQUENCE:
#	fcdir.py dir_fc dir_base
# INPUTS:
#	dir
#       dir_base
# CALLS:
# PROCEDURE:
# >	Implemented as a python script
# >	Files in directory 'dir' are compared with files
#	in directory 'dir_base' having the same base name
#	(file name, plus extension).
# MODIFICATION HISTORY:
#	MAY-2002, Paul Hick (UCSD/CASS)
#	FEB-2004, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
#		Added delete keyword; changed 'r' to 'br' in open
#		statements to allow for processing of binary files.
