LharcUUCP -- written by Peter Simons

                         Release 1 (6 April 1994)


    LharcUUCP is a small tool to speed your uucico transfers up. uucico's
performance goes down, when you have to transfer plenty of small files, like
e-mail and the corresponding description file. Larger files, however, are
transferred at satisfying speed and efficiency--at least with a larger block
size.

    The idea is to batch all your e-mail and to transfer this large file
rather than all of them separately. Additionally, this larger file can be
crunched much better than the smaller ones. Ideas like this are available
for several years now, namely BSMTP or RSMTP.

    But these methods have one significant disadvantage: Once, the mails are
batched, you can't add any files anymore! This means, that you can't run the
batcher several times a day without having several smaller files again. And
if you batch only a few times a day, you're stuck with certain poll-times.

    "So," I thought, "why not use lharc or any similar archiver?" These
archivers can crunch the data very well and they can still add files at a
later time. Additionally, lzh-archives are understood on virtually every
platform.

    This is what LharcUUCP does! It scans your spool directory for queued
jobs and archives them into one file using lharc. Currently, only mail- and
news jobs are processed. Future versions might batch UUCP file transfers,
too. Then an appropriate command- (`X.system*') and description file
(`D.systemX*') is created--to tell uucico what to do with the archive.

    In case, such an archive already exists when LharcUUCP is issued, it
adds the new jobs to that archives, *not* creating a second file to
transfer!

    On the other side of the transfer, an uuxqt that recognizes the new
job-type `rlharc' is required.
