[NTLUG:Discuss] change words on every line in a file

[Ralph Green]

Howdy,
  I would probably write a short Python program to do this.  If the
examples you have been given, then just use them.  If this is a
program you will be using often of for a long time, or you expect the
algorithm will need tweaking over time, then Python's readability is
an advantage to me.Ralph
