As corrected later in the thread, MrsEntity writes

"""
I have, in fact, this very afternoon, invented a means of writing a
carriage return character using only 2 bits of information. I am
prepared to sell licenses to this revolutionary technology for the
low price of $29.95 plus tax.

Sorry, that should've been a 500Mb, 2M line file.
"""

If only other unnamed persons on the list were so gracious rather
than turning the flame-dial to 11.

I hope that when people come to the list, *this* is what they see,
laugh, and want to participate.

Although, MrsEntity could be zombie David A. Huffman, whose encoding
scheme actually *can* store 2M lines in 500kb :-)
