 *  PROGRAM:  mvp - move with pattern, version 1.01
 *
 *  PURPOSE:  Rename a set of files according to a given pattern.
 *
 *  BLURB:    Are you tired of running into a situation where you have a
 *            bunch of files that you want to rename in the same way, but
 *            you have no tool to do that for you?  For instance, you might
 *            have a bunch of files 'data01.dat' to 'data99.dat' and you
 *            want to rename them to use four digits for the numbers.  Well,
 *            now you can.  This program will allow you to make simple
 *            changes to groups of filenames by allowing you to insert a
 *            common substring or cut one from a certain point in all of the
 *            filenames given.
