- BEFORE YOU ASK: UnZip, its companion utility Zip, and related utilities
- and support files can be found in many places; read the file "Where" for
- further details. To contact the authors with suggestions, bug reports, or
- fixes, continue reading this file (README) and the file "ZipRules". For
- a list of known bugs and possible future features, read "BUGS". And for a
- commented listing of the files included in the source distribution, read
- "Contents" in said distribution.
-
- ALSO NOTE: Info-ZIP's mailing addresses have changed! The most important
- one: zip-bugs@wkuvx1.bitnet (or zip-bugs%wkuvx1.bitnet@ukcc.uky.edu, for
- those without a direct Bitnet connection). See below for other addresses.

- This version of UnZip has been ported to a wide array of hardware--from
- micros to supercomputers--and operating systems: Unix (many flavors), VMS
- OS/2, Minix, MSDOS, Windows, NT, TOPS-20, Amiga, Atari TOS and Macintosh.
- Although highly compatible with PKWARE's PKZIP and PKUNZIP utilities of
- MSDOS fame, our primary objective has been one of portability and other-
- than-MSDOS functionality. Features not found in the PKWare version include
- default extraction of directory trees (with a switch to defeat this, rather
- than the other way around); VMS, Macintosh and OS/2 extended file attributes;
- and, of course, the ability to run under most of your favorite operating
- systems.
-
- See the main Contents file for a list of what's included. The individual
- OS Contents files (e.g., VMS/Contents) may list important compilation info
- in addition to explaining what files are what, so be sure to read them if
- you're not compiling under Unix.
-
- New features in this version include support for deflation (the new, high-
- performance compression method introduced in the PKZIP 1.93a beta); much
- faster decompression; relaxed copyright restrictions, due to rewritten
- code (see COPYING for details); multiple password guessing, for encrypted
- zipfiles; support for options stored in an environment variable, to change
- the default behavior; and a new Unix filter version of UnZip called FUnZip.
- Many bugs were fixed as well. The History file details the changes, and
- BUGS indicates the ones we haven't nailed just yet. :-)
-
- See unzip.1 or unzip.doc for usage (or zipinfo.1/zipinfo.doc for ZipInfo
- usage, or funzip.1/funzip.doc--do you sense a pattern here?--for FUnZip
- usage). Unfortunately the VMS versions of these documents are out of date
- now; we hope to correct this some day. :-)
-
- All bug reports and patches (context diffs only, please!) should go to
- zip-bugs@wkuvx1.bitnet, and suggestions for new features can be sent to
- info-zip@wkuvx1.bitnet (although we don't promise to use all suggestions).
- If it's something which is manifestly useful, sending the required patches
- to zip-bugs directly is likely to produce a quicker response than asking
- us to do it. Those directly responsible for updating the code are very
- short on time these days. If you're considering a port, however, please
- check in with Info-ZIP FIRST, since the code is constantly being updated
- behind the scenes. We'll arrange to send you the latest source. The
- alternative is the possibility that your hard work will be tucked away in
- a sub-archive and pretty much ignored.
-
- If you'd like to keep up to date with our UnZip (and companion Zip utility)
- development, join the ranks of BETA testers, add your own thoughts and con-
- tributions, etc., send a two-line mail message containing the commands HELP
- and LIST (on separate lines in the body of the message, not on the subject
- line) to listserv@wkuvx1.bitnet. You'll receive two messages listing the
- various Info-ZIP mailing-list formats which are available (and also various
- unrelated lists) and instructions on how to subscribe to one or more of them
- (courtesy of Hunter Goatley).
