This program was designed to allow computer users to exchange binary
files over computer networks that do not support the transmission of
binary data. This can be done by converting the binary file to an ASCII
file, then converting the ASCII file back to its original binary state
after transmission.

There are four popular methods of conversion; UUEncoding/UUDecoding,
MIME-Encoding/MIME-Decoding, BTOA-Encoding/BTOA-Decoding, and
SHIP-Encoding/SHIP-Decoding. Since each of these conversion methods is
an accepted standard, there are a wide variety of encoding/decoding
utilities for every computer platform.

If output size is not an issue, the best conversion method to use is
UUEncoding/UUDecoding. This method is fast, reliable, and allows large
files to be segmented (and re-assembled) automatically.

If output size is an issue, however, the best conversion method to use
is MIME-Encoding/MIME-Decoding. This conversion method is not very fast,
but produces very compact output. It is rapidly replacing UUEncoding/
UUDecoding as the conversion method of choice, because it is has all of
the power of UUEncoding/UUDecoding and is nearly as widely supported.
