xpkPWPK is being distributed under the comcept of Freeware. This means
that xpkPWPK may be freely distributed as long as no charge is made other
than to cover time and copying costs. If it is to be distributed via
floppy disk, this cost should be no higher than $3.00 (three) dollars US.
If distribution is via CDRom, the total cost should be no more than $25.00
(twenty-five) dollars US.
You may not copy and/or distribute this program without the accompanying
documentation unless you get permission from the author to do so. Fred
Fish and AmiNet already have my permission to include this program on their
CDRom collections.
You may not disassemble, decompile, re-source or otherwise reverse engineer
the program. If you wish to incorporate parts of this program into other
programs, write to the author to ask for permission.
Finally if you wish to include xpkPWPK on a disk magazine you are
REQUIRED to get the author's permission FIRST. Usually this will require
you to just send me a copy of the issue which contains xpkPWPK free
of charge.
Nico Francois has my permission to include xpkPWPK with any of his
programs.
I reserve the right to publically poke fun at anyone who fails to abide by
these distribution rules, along with more severe action if appropriate.
AmigaFormat magazine is forbiden to include xpkPWPK on its cover disks.

2- powerpacker.library
Copyright © by Nico Francois
------------------------------------------------------------------------
Installation
------------------------------------------------------------------------
Just
1) copy xpkPWPK.library or xpkPWPK030.library to
LIBS:Compressors/xpkPWPK.library
2) copy powerpacker.library to LIBS:
or
Use the provided installer script.
------------------------------------------------------------------------
Usage
------------------------------------------------------------------------
xpkPWPK allows you to select one of the five PowerPacker crunch
efficiencies and the three speedup buffer sizes by setting the xpk
efficiency number. The number (1-100) is translated as follows:
0-6 Fast - Small Buffer
7-13 Fast - Med Buffer
14-19 Fast - Large Buffer
20-26 Mediocre - Small Buffer
27-33 Mediocre - Med Buffer
34-39 Mediocre - Large Buffer
40-46 Good - Small Buffer
47-53 Good - Med Buffer
54-59 Good - Large Buffer (default)
60-66 Very good - Small Buffer
67-73 Very good - Med Buffer
74-79 Very good - Large Buffer
80-86 Best - Small Buffer
87-93 Best - Med Buffer
94-100 Best - Large Buffer
The size of the speedup buffer can be estimated from the following table:
Small Buffer from 3K (fast) to 33K (best)
Med Buffer from 5K (fast) to 65K (best)
Large Buffer from 196K (fast) to 256K (best)

Version 1.0 (14.08.95 17:45:50)
-----------------------------------------------------------
- Buffer size is now set by the efficiency value rather than
the env variable.
------------------------------------------------------------
Version 0.93 (20.05.95 14:19:11)
------------------------------------------------------------
- Added support for setting PowerPacker speedup buffer size
via environment variable.
------------------------------------------------------------
Version 0.92 (12.05.95 16:01:17)
------------------------------------------------------------
- library was not reporting that it had different packing
modes when queried, forgot XPKIF_MODES flag. (fixed)
Reported by David Balazic
- Added '030+ version of library
- Increse min in chunk to 64 bytes
------------------------------------------------------------
Version 0.91 (06.05.95 17:42:57)
------------------------------------------------------------
- Added support for PowerPacker encrypting of crunched data.
- Now crunch efficiency will be stored in the first chunk only
saving a few bytes in larger files.
------------------------------------------------------------
Version 0.90 (03.05.95 19:32:38)
------------------------------------------------------------
