- ARCHIVELISTER -

1.Overview
----------
AL is a utility designed for viewing the contents of archives generated by
file archiver like ARC, LHARC or PKAZIP. It can be used on FD-Disks where
large portions (e.g. source codes) are shipped in compressed form (think
of Fred's Library), or with BBS software to allow user to examine archives
before download.
2.Why use AL?
-------------
AL can be used to examine several different archive formats (see list)
although it is quite smaller than *ANY* of the archiver which's archives AL
is able to listen. AL is fully standalone and be used from Workbench as a
default tool for archives. AL is safe for use with certain corrupt
archives: Division by Zero hacks (think of the percentage generation),
"loop" archives (files with negative length cause some archiver to loop).
AL attempts to preserve the "look and feel" of the original archivers,
although it will provide as much information as possible.

3.5.Center of doc file
----------------------
This is (approx.) the center of the doc file.
4.CLI Usage
-----------
Very simple:
AL <archive-name>
AL will examine the archive type and output the contents, if possible. You
can redirect output to a file in order to output AL's listing to an online
user.
There may be certain errors which AL can display; normally you could guess
from the text itself: "backward skip" and "division by zero" denote
corrupt or bomb archives.
AL is fully "PURE" (thanks "cres.o") and can savely be made resident with
1.3 shell, 2.0 shell or the ARP resident manager.
5.WB Usage
----------
Set AL as your default tool for the archive files; if the user
double-clicks the archive's icon, AL will load, open a window and do the
same as it has been started from the CLI. AL will wait for a <RETURN>
before closing the window.
6.Supported Archives
--------------------
Currently supported are:
ARC
LHARC/LZ
PKAZIP/PKZIP
APE (percentage output is different, but that is a problem
of APE, not of AL :-)
ZOO (recognized, but not listed yet)
WARP (disk tracker)
ZAP (disk tracker)
ZOOM (disk tracker)
POWERPACKER datafiles
DMS (disk tracker)
More archiver and disk-tracker are planned for the future; if you have
information about archive formats, feel free to suply them to me so that I
can include that in future releases of AL.
