12: BEFORE YOU ASK: UnZip, its companion utility Zip, and related utilities
13: and support files can be found in many places; read the file "Where" for
14: further details. To contact the authors with suggestions, bug reports, or
15: fixes, continue reading this file (README) and the file "ZipRules". For
16: a list of known bugs and possible future features, read "BUGS". And for a
17: commented listing of the files included in the source distribution, read
18: "Contents" in said distribution.
19:
20: ALSO NOTE: Info-ZIP's mailing addresses have changed! The most important
21: one: [email protected] (or zip-bugs%[email protected], for
22: those without a direct Bitnet connection). See below for other addresses.

26: This version of UnZip has been ported to a wide array of hardware--from
27: micros to supercomputers--and operating systems: Unix (many flavors),
28: VMS, OS/2, Minix, MSDOS, Windows, NT, Amiga (partially) and Macintosh.
29: [The current 5.1 beta has additionally been ported to TOPS-20 and Atari
30: TOS, and the Amiga port has been completed.] Although highly compatible
31: with PKWARE's PKZIP and PKUNZIP utilities of MSDOS fame, our primary ob-
32: jective has been one of portability and other-than-MSDOS functionality.
33: Features not found in the PKWare version include default extraction of
34: directory trees (with a switch to defeat this, rather than the other way
35: around); VMS, Macintosh and OS/2 extended file attributes; and, of course,
36: the ability to run under most of your favorite operating systems.
37:
38: See the main Contents file for a list of what's included. The individual
39: OS Contents files (e.g., VMS/Contents) may list important compilation info
40: in addition to explaining what files are what, so be sure to read them if
41: you're not compiling under Unix.
42:
43: New features in this version include support for deflation (the new, high-
44: performance compression method introduced in the PKZIP 1.93a beta); much
45: faster decompression; relaxed copyright restrictions, due to rewritten
46: code (see COPYING for details); multiple password guessing, for encrypted
47: zipfiles; support for options stored in an environment variable, to change
48: the default behavior; and a new Unix filter version of UnZip called FUnZip.
49: Many bugs were fixed as well. The History file details the changes, and
50: BUGS indicates the ones we haven't nailed just yet. :-)
51:
52: See unzip.1 or unzip.doc for usage (or zipinfo.1/zipinfo.doc for ZipInfo
53: usage, or funzip.1/funzip.doc--do you sense a pattern here?--for FUnZip
54: usage). Unfortunately the VMS versions of these documents are out of date
55: now; we hope to correct this some day. :-)
56:
57: All bug reports and patches (context diffs only, please!) should go to
58: [email protected], and suggestions for new features can be sent to
59: [email protected] (although we don't promise to use all suggestions).
60: If it's something which is manifestly useful, sending the required patches
61: to zip-bugs directly is likely to produce a quicker response than asking
62: us to do it. Those directly responsible for updating the code are very
63: short on time these days. If you're considering a port, however, please
64: check in with Info-ZIP FIRST, since the code is constantly being updated
65: behind the scenes. We'll arrange to send you the latest source. The
66: alternative is the possibility that your hard work will be tucked away in
67: a sub-archive and pretty much ignored.
68:
69: If you'd like to keep up to date with our UnZip (and companion Zip utility)
70: development, join the ranks of BETA testers, add your own thoughts and con-
71: tributions, etc., send a two-line mail message containing the commands HELP
72: and LIST (on separate lines in the body of the message, not on the subject
73: line) to [email protected]. You'll receive two messages listing the
74: various Info-ZIP mailing-list formats which are available (and also various
75: unrelated lists) and instructions on how to subscribe to one or more of them
76: (courtesy of Hunter Goatley).
