5 UnZip - a zipfile extraction utility. See below for make instructions, or
6 read the comments in Makefile and the various Contents files for more de-
7 tailed explanations. To report a bug, send a *complete* description to
8 Zip-Bugs@lists.wku.edu; include machine type, operating system and ver-
9 sion, compiler and version, and reasonably detailed error messages or prob-
10 lem report. To join Info-ZIP, see the instructions in README.
11
12 UnZip 5.x is a greatly expanded and partially rewritten successor to 4.x,
13 which in turn was almost a complete rewrite of version 3.x. For a detailed
14 revision history, see UnzpHist.zip at quest.jpl.nasa.gov. For a list of
15 the many (near infinite) contributors, see "CONTRIBS" in the UnZip source
16 distribution.

20 [from original zipinfo.c]
21
22 This program reads great gobs of totally nifty information, including the
23 central directory stuff, from ZIP archives ("zipfiles" for short). It
24 started as just a testbed for fooling with zipfiles, but at this point it
25 is actually a useful utility. It also became the basis for the rewrite of
26 UnZip (3.16 -> 4.0), using the central directory for processing rather than
27 the individual (local) file headers.
28
29 As of ZipInfo v2.0 and UnZip v5.1, the two programs are combined into one.
30 If the executable is named "unzip" (or "unzip.exe", depending), it behaves
31 like UnZip by default; if it is named "zipinfo" or "ii", it behaves like
32 ZipInfo. The ZipInfo behavior may also be triggered by use of unzip's -Z
33 option; for example, "unzip -Z [zipinfo_options] archive.zip".

35 Another dandy product from your buddies at Newtware!
