/************************************************************************

This program can be compiled under either C or C++.
It copies its input to its output, substituting all old
NTL macro names by new NTL macro names.
This is intended to automate the transition from NTL 3.1 to 3.5.

Each maximal length alphanumeric substring in the input
is looked up in a table, and if there is a match, the substring
is replaced.
