X  Additional copyright information:
X
X     BILF (distributed with the VMS stuff) is copyrighted by Rahul Dhesi,
X     but it is freely distributable.
X
X     The functions extract_or_test_files() and store_info() in extract.c,
X     do_string() and return_VMS() in misc.c, VMS version of echo() in
X     file_io.c, and find_end_central_dir() in unzip.c, were written by
X     Greg Roelofs and subsequently modified by many others via Info-ZIP.
X     I do not claim a copyright on these routines, but I do ask that no
X     one else do so either, :-) and that anyone using them in other pro-
X     grams note their source.
X
X     The function decrypt_member() in extract.c and the password functions
X     in file_io.c were written by Mark Adler, as were the inflate.c and
X     explode.c modules.
X
X     The function mapped_name() in mapname.c was written by David Kirschbaum,
X     based on the XXU program by Frank Da Cruz.
X
X     The module match.c was written by J. Kercheval and modified by David
X     Kirschbaum for use in UnZip.
X
X     Original notes from unzip 2.0a by Carl Mascott, [e-mail]
X     (these are only the modifications which seem still to exist):
X        * 12/14/89  C. Mascott  2.0a   adapt for UNIX
X        *              don't pre-allocate output file space
X        *              implement -t, -v, member file specs
X        *              buffer all input
X        *              fix "Bad CRC" msg: good/bad CRCs were swapped
X        *              check for write error on output file
X
X     Most of the remaining routines have contributions from all of us, and
X     show it. :-)
X
X===============================================================================
X
X   Info-ZIP comments:
X
X   Info-ZIP has very little interest in legal matters, aside from the usual
X   "CYA" sense (that's an acronym, and you can figure it out yourself :-) ).
X
X   As far as we are aware--and please note that the numerous contributors
X   and copyright holders make this a little uncertain--the UnZip code is now
X   "clean" in the sense that an UnZip executable may be distributed with a
X   commercial product SO LONG AS IT IS CLEAR THAT UNZIP IS NOT BEING SOLD,
X   THAT THE SOURCE CODE IS FREELY AVAILABLE, AND THAT THERE ARE NO EXTRA OR
X   HIDDEN CHARGES RESULTING FROM ITS USE BY OR INCLUSION WITH THE COMMERCIAL
X   PRODUCT.  In particular, the retroactive copyright on unimplode.c which
X   Carl Mascott requested we include in UnZip 4.2 is no longer in force, since
X   Mark Adler has rewritten the module in question from scratch (it's about
X   twice as fast, too! :-) ).
X
X   Regarding the original copyright by Mr. Smith:  Info-ZIP has finally found
X   him again (he's moved to southern California), and he's apparently happy
X   with the current code and restrictions.  More specifically, since the
X   current incarnation of UnZip can be considered "our own"--it bears very
X   little resemblance to his original program, in either content or size :-)
X   --and since we freely distribute the source code, we believe that we are
X   within the bounds of his third stipulation.
X
X   Info-ZIP continues to rewrite portions of the code as time permits, in an
X   effort to eliminate as many of the restrictions (and bugs) as possible.
X   The bugs are our primary concern, however, so don't hold your breath. :-)

XSubject: Info-ZIP Rules (No Feelthy ...)
X
XIn discussions with Mark Adler (and others), I realized we in the Info-ZIP
Xcommunity have been evolving a set of rules that maybe oughtta be
Xdocumented, archived, and available to potential contributors.
X
XThe following appear to meet our requirements.  Please observe these
Xrules when submitting source, context diff, or other files to Info-ZIP.
X
X
X1 - "NO FEELTHY TABS"
X
X    Many editors and EMail systems either have no capability to use and/or
Xdisplay the Ascii 9 TAB character correctly, or there are variable tab
Xcolumns, or other horrors.  (My MaxEMail offline email editor for one.)
X
X    Bottom line:  use spaces, not tabs.
X
X    Related utility programs:  Unix and MS-DOS :  expand, unexpand.
XMS-DOS: Buerg's TABS; Toad Hall's TOADSOFT.  And some editors have the
Xconversion built-in.
X
X    Exceptions:  The Unix Makefile.  Some makes seem to require "real"
Xtabs.  If they need it there, fine.  So don't fiddle the Makefile.
X
X
X2 - "NO FEELTHY CRS"
X
X    All source, documentation and other text files shall have Unix style
Xline endings (LF, Ctrl-J), NOT the MS-DOS CR/LF or Mac CR line endings.
X
X    Reason:  "Real programmers" in any environment can convert back and
Xforth between Unix and DOS/Mac style.  MS-DOS Turbo C can use Unix or
XMS-DOS line endings (donno about Mac Turbo C).  Buerg's LIST file display
Xutility for MS-DOS can use Unix or MS-DOS line endings.  Unix utilities
Xlike diff and patch die a horrible death (or produce horrible output) if
Xtarget files have CRs.
X
X    Related utilities:  flip for Unix and MS-DOS.
X
X    Exceptions:  The zip archive README and zip.doc files, which Mark
XAdler wants to leave in MSDOS for "unsophisticated" (read brain-dead) DOS
Xusers.  Also the batch files to compile under MS-DOS (where it requires
Xthe CRs.)
X
X
X3 - "NO FEELTHY HEX"
X
X    We'll use uuencode/uudecode compatible converters to move binary files
Xthrough our 7-bit EMail systems (xxencode on special request).  Uuencoded
Xfiles, if larger than +/- 32Kb, will be broken into smaller (< 32Kb)
Xfiles (via David M. Read's UUXFER utility).
X
X    Reason:  to prevent sounds of gagging mailers from resounding
Xthroughout the land.  To be standard with the Uunet side of the world.
XTo be relatively efficient in the binary->Ascii conversion.  (Yeah, yeah,
XI know, there's better conversions out there.  But not as widely known.)
X
X    Related utilities:  uuencode, uudecode, uuxfer20, quux, others.
XJust make sure they don't leave imbedded or trailing spaces.  (E.g., they
Xshould use the "`" character in place of Ascii 32.)  Else mailers are
Xprone to truncate or whatever.  Message me if you need one.
X
X
X4 - "NO FEELTHY TARS"
X
X    unzip will be available in .tar.Z (16-bit compressed tar), .arc (as
Xavailable on Unix, SIMTEL20, PKPAK, etc., *NOT* the latest proprietary
XSEA version), or .zip format.  (If requesting we EMail you source,
Xspecify desired format.)  zip source will only be distributed in .zip
Xarchives.
X
X    Reason:  For unzip development or use, anyone should have one of the
Xspecified dearchivers.  For zip development or use, you shouldn't be
Xmessing with zip unless you can already unzip.  (This protects the
Xinnocent.)
X
X    Related utilities:  Unix:  arc, tar, compress, zip, unzip.  MS-DOS:
XPKUNPAK, PKUNZIP, PAK, TAR, COMPRESS, and others.
X
X    Exceptions:  EMail me directly for any special circumstances or
Xrequirements (zoo, BinHex, 12-bit compress, etc.)
X
X
X5 - "NO FEELTHY FANCY_NAMES"
X
X    Assume the worst:  that someone on a brain-damaged DOS system has to
Xwork with everything your magic fingers produced.  Keep the file names
Xunimaginative and within MS-DOS limits (e.g., ordinary A..Z, 1..9, "-$_!"
Xtype characters, in the "filename.typ" 8-dot-3 format).  MacUsers, giggle
Xall you want, but no spaces.
X
X    Reason:  Compatibility with different file systems.  MS-DOS is the
Xmost limited.
X
X
X6 - "NO FEELTHY GRAPHICS"
X
X    Do all your editing in a plain-text ASCII editor.  No WordPerfect,
XWord, WordStar document mode, or other word processor files, thenkyew.
XNo desktop publishing.  No TIFFs, no GIFs, no imbedded pictures or dancing
Xladies (too bad, Cave Newt).
X
X    Reason:  Compatibility with different consoles.  My old XT clone is
Xthe most limited!
X
X    Related utilities:  vi, ed, EDLIN, Turbo C editor, UED, EASYEDIT, cat
Xor "COPY CON UNZIP.C"; various word processor -> text conversion utilities.
X
X
X7 - "NO FEELTHY DASHES"
X
X    Don't have repeated dashes (starting at the left margin) in any
Xsource code or patches you try to EMail to me or Info-ZIP.  Instead, be
Xsure to always prefix them with a space, asterisk, comment, whatever, like
Xthis:
X#---------------   or
X/*--------------   or even
X ---------------   (just indented)
X
X    Reason:  Most "undigestify" utilities (that break down newsletters
Xinto their separate messages) use that "--------" (starting at the left
Xmargin) as the symbol that it's hit the end of a message.  I'd rather not
Xhave your C source file broken up into a dozen separate untitled messages
Xin my mail system, thank you.  I'll be going through the unzip source Any
XDay Now and changing anything like that by indenting, prefixing, whatever.

X.SH DESCRIPTION
X.I UnZip
Xwill list, test, or extract from a ZIP archive, commonly found on MSDOS
Xsystems.
XArchive member extraction is implied by the absence of the \-c, \-p,
X\-t, \-l, \-v or \-z options.  All archive members are processed unless a
X.I filespec
Xis provided to specify a subset of the archive members.  The
X.I filespec
Xis similar to an egrep expression, and may contain:
X.sp 1
X.ta \w'[...]'u+2m
X*    matches a sequence of 0 or more characters
X.br
X?    matches exactly 1 character
X.br
X\\nnn    matches the character having octal code nnn
X.PD 0
X.IP [...] \w'[...]'u+2m
Xmatches any single character found inside the brackets; ranges
Xare specified by a beginning character, a hyphen, and an ending
Xcharacter.  If an exclamation point or a carat (`!' or `^') follows
Xthe left bracket, then the range of characters matched is complemented
Xwith respect to the ASCII character set (that is, anything except the
Xcharacters inside the brackets is considered a match).
X.PD
X.SH ENVIRONMENT OPTIONS
X\fIUnZip\fP's default behavior may be modified via options placed in
Xan environment variable.  This can be done with any option, but it
Xis probably most useful with the
X\-q, \-o, or \-n modifiers:  in order to make \fIUnZip\fP quieter by
Xdefault, or to make it always overwrite or never overwrite files as it
Xextracts them.  For example, to
Xmake \fIUnZip\fP act as quietly as possible, only reporting errors, one would
Xuse one of the following commands:
X.ta \w'tabset'u +\w'UNZIP=-qq; export UNZIP'u+4m
X.PP
X.IP "\tsetenv UNZIP -qq\tUnix C shell"
X.br
X.IP "\tUNZIP=-qq; export UNZIP\tUnix Bourne shell"
X.PP
X.IP "\tset UNZIP=-qq\tOS/2 or MS-DOS"
X.PP
X.IP "\tdefine UNZIP_OPTS ""-qq""\tVMS (quotes for LOWERCASE)"
X.PP
XEnvironment options are, in effect, considered to be just like any other
Xcommand-line options, except that they are effectively the first options
Xon the command line.  To override
Xan environment option, one may use the ``minus operator'' to remove it.  For
Xinstance, to override one of the quiet-flags in the example above, use the
Xcommand
X.PP
X.IP "\t\fIunzip\fP \-\-q[other options] zipfile"
X.PP
XThe first hyphen is the normal
Xswitch character, and the second is a minus sign, acting on the q option.
XThus the effect here is to cancel a single quantum of quietness.  To cancel
Xboth quiet flags, two (or more) minuses may be used:
X.PP
X.IP "\t\fIunzip\fP \-x\-\-q zipfile"
X.PP
Xor
X.PP
X.IP "\t\fIunzip\fP \-\-\-qx zipfile"
X.PP
X(the two are equivalent).  This may seem awkward
Xor confusing, but it is reasonably intuitive:  just ignore the first
Xhyphen and go from there.  It is also consistent with the behavior of Unix
Xnice(1).
X.PD
X.SH EXAMPLES
XTo use \fIUnZip\fP to extract all members of the archive letters.zip,
Xcreating any directories as necessary:
X.PP
X.IP "\t\fIunzip\fP letters"
X.PP
XTo extract all members of letters.zip to the current directory:
X.PP
X.IP "\t\fIunzip\fP -j letters"
X.PP
XTo test letters.zip, printing only a summary message indicating
Xwhether the archive is OK or not:
X.PP
X.IP "\t\fIunzip\fP -tq letters"
X.PP
XTo extract to standard output all members of letters.zip whose names end
Xin ``.tex'', converting to the local end-of-line convention and piping the
Xoutput into more(1):
X.PP
X.IP "\t\fIunzip\fP \-ca letters \e*.tex | more"
X.PP
X(The backslash before the asterisk is only required if the shell expands
Xwildcards, as in Unix; double quotes could have been used instead, as in
Xthe source example below.)\ \ To extract the binary file paper1.dvi to
Xstandard output and pipe it to a printing program:
X.PP
X.IP "\t\fIunzip\fP \-p articles paper1.dvi | dvips"
X.PP
XTo extract all FORTRAN and C source files--*.f, *.c, *.h, Makefile (the
Xdouble quotes are necessary only in Unix and only if globbing is turned on):
X.PP
X.IP "\t\fIunzip\fP source.zip ""*.[fch]"" Makefile"
X.PP
XTo extract only newer versions of the files already in the current directory,
Xwithout querying (NOTE:  be careful of unzipping in one timezone a zipfile
Xcreated in another--ZIP archives contain no timezone information, and a
X``newer'' file from an eastern timezone may, in fact, be older):
X.PP
X.IP "\t\fIunzip\fP \-fo sources"
X.PP
XTo extract newer versions of the files already in the current directory and
Xto create any files not already there (same caveat as previous example):
X.PP
X.IP "\t\fIunzip\fP \-uo sources"
X.PP
X.PP
XIn the last five examples, assume that UNZIP or UNZIP_OPTS is set to -q.
XTo do a singly quiet listing:
X.PP
X.IP "\t\fIunzip\fP \-\fIl\fP \fIfile\fP"
X.PP
XTo do a doubly quiet listing:
X.PP
X.IP "\t\fIunzip\fP \-\fIql\fP \fIfile\fP"
X.PP
XTo do a standard listing:
X.PP
X.IP "\t\fIunzip\fP \-\-\fIql\fP \fIfile\fP"
X.PP
Xor
X.PP
X.IP "\t\fIunzip\fP \-\fIl\fP\-\fIq\fP \fIfile\fP"
X.PP
Xor
X.PP
X.IP "\t\fIunzip\fP \-\fIl\fP\-\-\fIq\fP \fIfile\fP"
X.PP
X(extra minuses don't hurt).
X.PD
X.SH TIPS
XThe current maintainer, being a lazy sort, finds it very useful to define
Xan alias ``tt'' for ``unzip -tq''.  One may then simply type ``tt zipfile''
Xto test the archive, something which one ought make a habit of doing.
XWith luck \fIUnZip\fP will report ``No errors detected in zipfile.zip,''
Xafter which one may breathe a sigh of relief.
