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!
