/*
version 0.36
* Unicode support by Jim Park -- 08/27/2007
* This support allow Unicode *ZIP file* names but does NOT allow the archive
* to store Unicode files inside it.  That's a ZLIB limitation that I can't
* do much about.

version 0.35
* drag & drop support

version 0.34
* preserve zip timestamps

version 0.33
* Added solid compression checkbox

version 0.32
* Fixed codepage problems

version 0.31 (by Joost Verburg)
* LZMA compression support
* Fixed compression setting

version 0.31 (by Joost Verburg)
* Based on header files
* Improved interface
* Modern UI support
* New script code
* Immproved folder detection
