Dave,

The Archive Server invokes a faithful version of ARC 5.10, but with an
added option to significantly speed up the processing: the Q (for
Quick) option, which bypasses all the tests of the various
compression techniques and unconditionally compresses the input file.
That compression uses a 12-bit mode vs. the 16-bit mode used by the
Unix compress program.

The uuencode algorithm is built directly into the server program.  It
has been slightly modified to append a trailing "M" to each line of
output to preserve any trailing spaces resulting from the uuencode
process.  This change was made expressly for the BITNET recipients
whose mailers want to suppress those trailing blanks.  A properly
implemented uudecode will ignore those trailing Ms.
