X UnZip - a zipfile extraction utility. See below for make instructions, or
X read the comments in Makefile and the various Contents files for more de-
X tailed explanations. To report a bug, send a *complete* description to
X zip-bugs@wkuvx1.wku.edu; include machine type, operating system and ver-
X sion, compiler and version, and reasonably detailed error messages or prob-
X lem report. To join Info-ZIP, see the instructions in README.
X
X UnZip 5.x is a greatly expanded and partially rewritten successor to 4.x,
X which in turn was almost a complete rewrite of version 3.x. For a detailed
X revision history, see UnzpHist.zip at quest.jpl.nasa.gov. For a list of
X the many (near infinite) contributors, see "CONTRIBS" in the UnZip source
X distribution.

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