MacZip is a cross-platform compatible tool and includes both Zip (for compression) and Unzip (for extraction).
zip is a compression and file packaging utility for Unix, VMS, MSDOS, OS/2, Windows NT, Minix, Atari and Macintosh, Amiga and Acorn RISC OS.
Unzip unpacks zip archives.
The zip and unzip programs can work with archives pro- duced by PKZIP, and PKZIP and PKUNZIP can work with archives produced by zip. zip version 2.2 is compatible with PKZIP 2.04.
This port supports also Apple-event.So you can install it in your WWW-Browser as a helper-app. A additional apple event "do_cmd" gives you the full power of command-line invocation via applescript.
