// This program will diff two lef files or two def files and list the
// different between the two files.  This problem is not intend to
// diff a real design.  If user runs this program will a big design,
// they may experience long execution time and may even ran out of
// memory.
//
// This program is to give user a feel of whether they are using the
// parser correctly.  After they read the lef/def file in, and
// write them back out in lef/def format.
//
// This program support lef/def 5.6.
