- LharcUUCP -- written by Peter Simons

- What is it?
- ***********
-
- 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 blocksize.
-
- The idea is to batch all your e-mail and to transfer this large file
- rather than all of them seperatly. 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 appropiate 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, a new uuxqt is required, which
- recognizes the archive type and handles it correctly, but that is a very
- small and easy addition.
