  unzip.c

  UnZip - a zipfile extraction utility.  See below for make instructions, or
  read the comments in Makefile and the various Contents files for more de-
  tailed explanations.  To report a bug, submit a *complete* description via
  //www.info-zip.org/zip-bug.html; include machine type, operating system and
  version, compiler and version, and reasonably detailed error messages or
  problem report.  To join Info-ZIP, see the instructions in README.

  UnZip 5.x is a greatly expanded and partially rewritten successor to 4.x,
  which in turn was almost a complete rewrite of version 3.x.  For a detailed
  revision history, see UnzpHist.zip at quest.jpl.nasa.gov.  For a list of
  the many (near infinite) contributors, see "CONTRIBS" in the UnZip source
  distribution.

  UnZip 6.0 adds support for archives larger than 4 GiB using the Zip64
  extensions as well as support for Unicode information embedded per the
  latest zip standard additions.

  ---------------------------------------------------------------------------

  [from original zipinfo.c]

  This program reads great gobs of totally nifty information, including the
  central directory stuff, from ZIP archives ("zipfiles" for short).  It
  started as just a testbed for fooling with zipfiles, but at this point it
  is actually a useful utility.  It also became the basis for the rewrite of
  UnZip (3.16 -> 4.0), using the central directory for processing rather than
  the individual (local) file headers.

  As of ZipInfo v2.0 and UnZip v5.1, the two programs are combined into one.
  If the executable is named "unzip" (or "unzip.exe", depending), it behaves
  like UnZip by default; if it is named "zipinfo" or "ii", it behaves like
  ZipInfo.  The ZipInfo behavior may also be triggered by use of unzip's -Z
  option; for example, "unzip -Z [zipinfo_options] archive.zip".

  Another dandy product from your buddies at Newtware!
