-
- 'UnZip' is a small Zipfile extract utility. It is written to be as
- small and portable as possible -- ideal as a starting point for handling
- .ZIP files in non-IBM environments.
-
- Source code is provided in C and Turbo Pascal. If you port this program
- to a non-IBM system, I would appreciate a copy of the ported source and
- exec files.

- Usage

- Revision history
- ----------------
-
- 3-3-89
- Initial alpha test release.
-
- 3-5-89
- First fully operational release. Does not implement CRC verification,
- but should correctly unzip all compression methods.
-
- 3-6-89
- Corrected end-of-file detection in both shrink and reduce expanders.
- Resulting files should now always have the correct size. Added ".ZIP"
- default to unzip.c to match calling conventions of unz.pas.
-
- 3-8-89
- Moved machine and operating-system specific code to a block starting
- around line 180. Added code to swap bytes on host machines that
- store the high order bytes in lower address locations than the low
- order bytes.
-
- 3-15-89
- Added CRC checking in UNZIP.C. Speeded operation by about 150%.
-
- I'm spending my time on the C version now and don't plan to do any
- further work on the pascal. If you're using the pascal version
- please contact me.
-
- 9-9-89
- Addition of new "un-implode" logic to handle new compression format
- included with PKZ101.
