- 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, send a *complete* description to
- Zip-Bugs@lists.wku.edu; include machine type, operating system and ver-
- sion, compiler and version, and reasonably detailed error messages or prob-
- lem 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.
- ---------------------------------------------------------------------------
- [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!
