- xpkPWPK is being distributed under the comcept of Freeware. This means

- 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

- 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)
- ------------------------------------------------------------
