- 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 and ftp site will be changing
- within the next month. The current e-mail addresses should hold for a
- while via mail-forwarding, but watch for the new addresses in our next
- release.

- This version of UnZip has been ported to a wide array of Unix and other
- mainframes, minis, and micros (including VMS, OS/2, Minix, MSDOS, Windows,
- Amiga (not tested recently), and Macintosh). Although highly compatible
- with PKware's PKZIP and PKUNZIP utilities of MSDOS fame, our primary ob-
- jective 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 1.93 alpha); 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.man for usage (or zipinfo.1/zipinfo.man for ZipInfo
- usage, or funzip.1/funzip.man--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 Unfortunately the VMS versions of these documents are out of date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 soon.
-
- All bug reports and patches (context diffs only, please!) should go to
- zip-bugs@cs.ucla.edu, and suggestions for new features can be sent to
- info-zip@cs.ucla.edu (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 somewhat
- 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 your request to Info-ZIP-Request@cs.ucla.edu and
- Rich Wales will add you to the Info-ZIP newsletter mailing list.
