description="
A utility for extracting ZIP files.

UnZip is an extraction utility for archives compressed in .zip format
(also called \"zipfiles\").  Although highly compatible both with
PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own
Zip program, our primary objectives have been portability and non-MSDOS
functionality.
