What is it?  A way to send binary files over older transport mechanisms.


Lets say you have a binary file named "ieee.jpg" that you want to send,
but you don't have FTP.  All you have is 'cat' and 'mail(x)'.  Here's 
what you do.

1.  Encode the file:
uuencode ieee.jpg ieee.jpg > ieee.uu

The reason there are two ieee.jpgs in the command line is that the first refers
to the file we are encoding and the second refers to the filename we want it to
decode to at the other end.

2. Send the file:
mail gm01@somewhere.com < ieee.uu
cat ieee.uu | mail -s'file attached' gm01@somewhere.com
...whatever...

3. On the other end, save the file and decode it:
uudecode ieee.uu

As simple as that. Now gm01 will have the file ieee.jpg on the other end.
