/* Copyright 1994 Anthony Lawrence

Archives files to a date, sequence  number format.

For example, IBCOPY DT *.DAT produces (assuming today is 12/31/94)

941231DT.001
941231DT.002
941231DT.003  and so on.  You can add a directory argument also:

IBCOPY MF *.GIF \MYSTUFF produces

\MYSTUFF\941231MF.001
\MYSTUFF\941231MF.002

Note that this is not written to support more than 999 files
being copied with the same tag and directory.  You could
easily modify this to use .aaa, etc. if you want.
