Wales, Jean-loup Gailly, XKai Uwe Rommel and Igor Mandrichenko. XPermission is granted to any individual or institution to use, copy, or Xredistribute this software so long as all of the original files are included Xunmodified, that it is not sold for profit, and that this copyright notice Xis retained. X X XZip 1.9 is a compression and file packaging utility. It is analogous to a Xcombination of tar and compress and is compatible with PKZIP 1.93a X(Phil Katz ZIP) for MSDOS systems. There is a companion to zip called Xunzip (of course) which you should be able to find the same place you Xgot zip. (See the file 'where' for details on ftp sites and mail Xservers.) X XThis version of zip has been ported to a wide array of Unix and other Xmainframes, minis, and micros including VMS, OS/2, Minix, MSDOS, XWindows NT, Atari, and Macintosh (the latter two have not been tested Xrecently). Although highly compatible with PKware's PKZIP and PKUNZIP Xutilities of MSDOS fame, our primary objective has been one of Xportability and other-than-MSDOS functionality. Features not found in Xthe PKWare version include creation of zip files in a pipe or on a Xdevice, VMS and OS/2 extended file attributes, conversion from Unix to XMSDOS text file format; and, of course, the ability to run on most of Xyour favorite operating systems. And it's free. X XIf you got this file from zip19.zip, you can extract the rest only Xwith unzip 5.0 or pkzip 1.93a. See the file 'Where' if you do not Xhave them already. X XPlease read the file install.doc for information on how to compile and Xinstall zip, zipsplit and zipnote. Please read the file zip.doc for Xinformation on how to use them. The file "contents" is a complete Xlist of the files you should have in this distribution. Also, if you Xare using MSDOS, you should read the note on file formats at the end Xof the contents file. X XThis version supports encryption, but the encryption code is distributed Xseparately because of the US export regulations. See the file 'Where' Xfor access to the encryption code. Decryption can be made with unzip 5.0 Xor later, or with zipcloak (which is provided in the encryption supplement). X XAll bug reports and patches should go to zip-bugs@cs.ucla.edu, and Xsuggestions for new features can be sent to info-zip@cs.ucla.edu X(although we don't promise to use all suggestions). Patches should be Xsent as context diffs only (diff -c). X XIf you're considering a port, please check in with zip-bugs FIRST, Xsince the code is constantly being updated behind the scenes. We'll Xarrange to give you access to the latest source. The alternative is the Xpossibility that your hard work will be tucked away in a sub-archive Xand pretty much ignored. A port to VM/CMS would be welcome. X XIf you'd like to keep up to date with our zip (and companion unzip utility) Xdevelopment, join the ranks of BETA testers, add your own thoughts and Xcontributions, etc., send your request to Info-ZIP-Request@cs.ucla.edu and Xyou will be added to the Info-ZIP newsletter mailing list. X X XIMPORTANT NOTES: X X- pkzip 1.93a is only an alpha version (see historical notes below). If X you wish to create zip files compatible with the official version of X pkzip (1.10), you must use zip 1.0. zip 1.9 cannot create files X with the old compression method (implosion). X X- zip 1.9 is is compatible with pkzip 1.93a, except when two features X are used: encryption or zip file created in a pipe or on a non X seekable device. pkzip versions of 2.0 will support such files, and X unzip 5.0 already supports them. (Thanks to Phil Katz for accepting X our suggested minor changes to the zip file format.) X X- the ports to the Macintosh and the Atari ST have been provided in X the hope that they can be useful, but they have been adapted from an X older version of zip (1.0) and are still completely untested. A X makefile is still missing for the Mac. Another Macintosh port is X being made by Johnny Lee <johnnyl@microsoft.com> but it requires X more substantial changes so it will be distributed separately. X X- Please read the file zip.doc, and in particular its list of known bugs X at the end. X XHistorical notes: X XAt the time of release of zip 1.9, the official released version of XPKZIP is version 1.10. PKZIP 1.93a is only an alpha version, which was Xreleased in October 1991. It was supposed to be replaced soon after Xwith an official release of pkzip 2.0. However, Phil Katz has not yet Xannounced a release date at the time of writing (Aug 19th, 1992). X XBeta versions of zip compatible with pkzip 1.93a have been available Xsince February 1992 to the info-zip group (see the file 'history'). XThe zip authors would have preferred to release zip 2.0 only after Xpkzip 2.0(*), to ensure full compatibility in case of archive format Xchanges between pkzip 1.93a and 2.0. However we feel that we cannot Xdelay any further the release of zip 1.9, since all the major features Xthat we wanted to put in are now available and well tested by the Xinfo-zip group. X X(*) The version number for the new pkzip was planned to be 2.00, but may X be increased to a number greater than 2.2 to prevent confusion with X several bogus versions, which may destroy all the data on your hard X disk if you run them.

It finds duplicated strings in the input data. The Xsecond occurrence of a string is replaced by a pointer to the previous Xstring, in the form of a pair (distance, length). Distances are Xlimited to 32K bytes, and lengths are limited to 258 bytes. When a Xstring does not occur anywhere in the previous 32K bytes, it is Xemitted as a sequence of literal bytes. (In this description, X'string' must be taken as an arbitrary sequence of bytes, and is not Xrestricted to printable characters.) X XLiterals or match lengths are compressed with one Huffman tree, and Xmatch distances are compressed with another tree. The trees are stored Xin a compact form at the start of each block. The blocks can have any Xsize (except that the compressed data for one block must fit in Xavailable memory). A block is terminated when zip determines that it Xwould be useful to start another block with fresh trees. (This is Xsomewhat similar to compress.) X XDuplicated strings are found using a hash table. All input strings of Xlength 3 are inserted in the hash table. A hash index is computed for Xthe next 3 bytes. If the hash chain for this index is not empty, all Xstrings in the chain are compared with the current input string, and Xthe longest match is selected. X XThe hash chains are searched starting with the most recent strings, to Xfavor small distances and thus take advantage of the Huffman encoding. XThe hash chains are singly linked. There are no deletions from the Xhash chains, the algorithm simply discards matches that are too old. X XTo avoid a worst-case situation, very long hash chains are arbitrarily Xtruncated at a certain length, determined by a runtime option (zip -1 Xto -9). So zip does not always find the longest possible match but Xgenerally finds a match which is long enough. X Xzip also defers the selection of matches with a lazy evaluation Xmechanism. After a match of length N has been found, zip searches for a Xlonger match at the next input byte. If a longer match is found, the Xprevious match is truncated to a length of one (thus producing a single Xliteral byte) and the longer match is emitted afterwards. Otherwise, Xthe original match is kept, and the next match search is attempted only XN steps later. X XThe lazy match evaluation is also subject to a runtime parameter. If Xthe current match is long enough, zip reduces the search for a longer Xmatch, thus speeding up the whole process. If compression ratio is more Ximportant than speed, zip attempts a complete second search even if Xthe first match is already long enough.

You will need Unzip 5.0 (under Unix, MSDOS, X or VMS) or PKUNZIP 1.93a (under MSDOS) to unpack the distribution X file, zip19.zip. But since you read this, you have unpacked it X already, or you cheated and got a tar.Z file... X X Let's assume however that you start from scratch and have not yet X unpacked the sources. First, unpack the source as follows, X assuming that you have zip19.zip in the current directory. X X mkdir zipsrc X cd zipsrc X unzip ../zip19 X X This extracts all source files and documentation in the X directory called "zipsrc". If you wish to build a version X of zip with encryption capabilities, you must also get the X separate package zcrypt19.zip and uncomment the definition X of MAKE at the beginning of the makefile. X X You then do: X X make system X X where "system" is one of: bsd, bsdold, sysv, sysv_386, sysv_old, sun, X sun_gcc, next, next10, hpux, dnix, cray, 3b1, zilog, aux, convex, aix, X minix, isc, dynix, ultrix, dec_osf1 or xos. If you are using a NeXT X running version 2.0 or greater, then make next. If you are using 1.0, X then make next10. If you are using Sun OS 4.x, then make sun (or X sun_gcc if you use gcc). If you are using SVR4 on a 386, use X sysv_386 to get the optimized asm code. X X The other special systems are HPUX, DNIX 5.2 or 5.3, Cray Unicos, X AT&T 3B1 (also known as Unix PC or PC 7300), Zilog Zeus, A/UX, X Convex, AIX, MINIX, ISC System V/386, Dynix, Ultrix and DEC OSF/1. X X Otherwise, if you are using BSD Unix, try bsd. If the linker X cannot find _memset or _memcpy, try bsdold. If you are using X System V Unix or SCO Unix, try sysv or sysv_old. Also use sysv X on a Silicon Graphics (SGI) machine. You can also cross-compile X Zip for MSDOS under SCO 386 Unix using "make scodos". X X If none of these compiles, links, and functions properly on X your Unix system, see the section BUGS below for how to get X help. X X If the appropriate system was selected, then the executables X zip, zipnote and zipsplit will be created. You can copy them X to an appropriate directory in the search path using: X X make install X X The defaults are /usr/local/bin for the executables and X /usr/man/man1 for the manual page. Change the macros BINDIR X and MANDIR in makefile if appropriate. X X You can use the command "set" to see the current search X path. If you are using the C-Shell (csh), enter the com- X mand: X X rehash X X so csh can find the new command in the path. You are now X ready to use Zip. X X You can get rid of the now unnecessary source and object X files with: X X cd .. X rm -r zipsrc X X This will remove the directory zip and its contents created X by unzip. You should keep the zip19.zip file around though, X in case you need to build it again or want to give it to a X colleague. X X The steps for installation under MSDOS, OS/2, and VMS are X similar to the above: first unzip the distribution files X into their own directory. The system dependant files are X stored in special subdirectories. You may have to X copy or move them to the main sources directory. X Then under MSDOS do one of: X X make makefile.msc X make -fmakefile.bor X X for Microsoft or Borland C++, respectively. For Turbo C 2.0, X use the configuration file tcconfig.tc, the batch file X doturboc.bat and the project files zip.prj, zipnote.prj X and zipsplit.prj. Make sure to use the compact model. X X Under OS/2: X X nmake -f makefile.os2 X X for Microsoft C 6.00. Under VAX VMS: X X @make_vaxc X or: @make_gcc X X For command help on any of the zip* utilities, simply enter X the name with no arguments.
