* LzhIt performs several tasks, including conversion archiving,
* correcting FILES.BBS (standard-type), internal correction, and much
* more (directory conversion, et cetera)!

DETAILED FIX REPORT:
06/07/89│ Repaired P│CLEANSEDIRECTORY which led to the disaster
3.30 pm │ in P│DELETEDIRECTORY. Occasionally ATTR│HIDDEN files
│ were created by archive protocol. P│DELETEDIRECTORY
│ only knew how to delete ATTR│ARCHIVE. I simply wrote
│ a new engine to delete ATTR│ANYFILE.
06/11/89│ Wrote P│WRITESTAMP which will properly TimeStamp newly
7.30 pm │ created LZHs.
06/11/89│ I completely redesigned the LoTek conversion method I
7.30 pm │ previously had used, and I plan to finish my other "*"
│ promises as soon as possible.

REGARDING ARCHIVING PROGRAMS
In recognition of the wide variety of needs, desires and opinions
within, my personal view-point is, and its a bloody obvious one,
that Haruyasu Yoshizaki's compression method is the most optimal,
and should be used by System Operators everywhere.
However, since it is the earnest desire of the current developers
and documenters to avoid participation as a unit in actions or
choices regarding compression which are motivated by network
politics. I will be writing a Compression ToolKit (MashIt), in
the near future that will allow users to easily convert from any
one method to any other method of compression. Until then, hey,
you might just go ahead and use LzhIt. You know how I personally
feel!
ANTINEOPHYTE TECHNORATA:
LZH by Japanese programmer Haruyasu Yoshizaki; After reading
"A Hard Disk Cookbook" from Shouei Press, Yoshi was exposed to
Miki's LArc, which surpasses PKware compression ratios. His next
shock was an even better ratio performance! -- Okumura's LZari,
an assembly written compression method. So, Yoshi once again, hit
the networks looking for an alternative -- using adaptive Huffman
coding with LZSS encoder (to achieve similar ratios with shortened
decompression time.
PAK by Nogate Consulting; ARC popularized the LZW method, which
substitutes 9-12 bit codes. PKARC made a simple modification to
the compression algorithm in ARC, by allowing 9-12 bit codes, and
hence doubling the number of allowable codes. PAK, on the other
hand, makes some radical changes to the LZW. PAK increases the
range from 2-13 bits instead of 9-13, dynamically altering the
compression method based on the local nature of data, and drops
only the least used codes when the code table fills, instead of
all of them as ARC and PKARC do. As a result, PAK performs better
on very large files, very small files, and on difficult files of
any length.
ZIP by Phil Katz (PKware); Shrinking is a Dynamic Ziv-Lempel-Welch
compression algorithm with partial clearing. The initial code size
is 9 bits, and the maximum code size is 13 bits. Shrinking differs
from conventional Dynamic Ziv-lempel-Welch implementations in
several respects: The Reducing algorithm is actually a combination
of two distinct algorithms. The first algorithm compresses
repeated byte sequences, and the second algorithm takes the
compressed stream from the first algorithm and applies a
probabilistic compression method.
ARC by Phil Katz (PKware); No information found as of this time.
ZOO by Rahul Dhesi; No information found as of this time.
