# Revision 1.2  1997/06/21 16:28:41  joi
# Added smarts for file testing and a default pattern.
#
# Revision 1.1  1997/05/24 20:48:37  joi
# Initial revision
#
#
# usage: prettycomp "pattern" File1 File2
#
# compares source lines extracted from two pretty 
# source files.  Parm one is a perl pattern that
# picks the lines you want to display.  A generic
# pattern would be "[^@&]" which gets everything
# that would create an attribute.  The next two
# parms are the files to compare.
#
# files are left behind on /tmp.
