|
** pkzip 2.0 file compression.
|
|
**
|
|
** Some of the code has been inspired by other open source projects,
|
|
** (mainly Info-Zip and Gilles Vollant's minizip).
|
|
** Compression and decompression actually uses the zlib library.

we use a 256K buffer here - if you want to use this code on a pre-iceage mainframe please change it ;)
