auto-numbering stamp

[Seth Teller <teller@lcs.mit.edu>]

i got two of these for our project.  it's 
an ink stamp that prints a six-digit 
number on your document, then advances
to the next number.  so we can stamp our
first million documents !

if we can choose an obscure ink color,
and get the s/w to find and OCR this
number on every doc, it's a nice
cross-check for various purposes 
(that we haven't lost documents; a help
to retrieve the paper copy from dead
storage; etc.).

seth.
