Slackware 13.0slackware-13.0

Wed Aug 26 10:00:38 CDT 2009
Slackware 13.0 x86_64 is released as stable!  Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits.  The ISOs are off to the replicator.  This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com.  Please consider
picking up a copy to help support the project.  Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy!  -P.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.

+These are the latest versions of the XV jumbo patches I originally created
+in February 2000 (but never distributed) and eventually updated and released
+in May 2004, prompted by a discussion on LWN (http://lwn.net/Articles/76391/).
+Information about the patches, updates to the patches, and the patches
+themselves can all be found here:
+
+	http://pobox.com/~newt/greg_xv.html
+	http://freshmeat.net/projects/xvjumbopatches/
+
+(Use the "Subscribe to new releases" link on the latter page if you want to
+be notified of new versions automatically; trivial registration required.)
+
+These two patches incorporate all of the fix- and enhancement-patches
+available from John's XV site (http://www.trilon.com/xv/downloads.html
+and ftp://ftp.trilon.com/pub/xv/patches/), plus a number of my own fixes
+and additions, plus quite a few from other people--though not all of the
+ones I'd intended to, due to lack of time after dealing with the latest
+set of security issues (one of which I discovered, sigh).  They're still
+not fully complete, and it's possible they never will be, but I do plan
+to continue tinkering with them whenever the mood strikes--and I may even
+release them publicly on rare occasions.  (At the current rate, it looks
+like once a year may be the best we can hope for...we'll see.)
+
+Also be aware that several other people have had the same idea over the
+years.  Ones I've found, more or less by accident, include:

+
+I very much doubt that this is an exhaustive list.  So far, most of the
+other patch-sets appear not to be as extensive or as up-to-date as my own,
+particularly now that the (very large) "Japanese extension" patches are
+incorporated--big thanks to Werner Fink of SuSE for that!
+
+Below I summarize the component patches that are encompassed by my jumbo
+bugfixes and jumbo enhancements patches.  Unfortunately, some of my own
+additions never saw the light of day as standalone patches, but considering
+the number of overlaps (collisions) already implicit in this list, it would
+have been difficult to accomplish even if I'd had the time.
+
+Here's a quick guide to the "third-party" credits in the lists below:
+
+  AAC = Andrey A. Chernov [ache]
+        (http://cvsweb.freebsd.org/ports/graphics/xv/files/patch-ab)
+  AD  = Andreas Dilger (adilger clusterfs.com)

+  GV  = Guido Vollbeding (http://sylvana.net/guido/)
+  IM  = IKEMOTO Masahiro (ikeyan airlab.cs.ritsumei.ac.jp)
+  JCE = John C. Elliott (http://www.seasip.demon.co.uk/ZX/zxdload.html)
+  JHB = John H. Bradley, of course (http://www.trilon.com/xv/)
+  JPD = Jean-Pierre Demailly (http://www-fourier.ujf-grenoble.fr/~demailly/)
+  JR  = John Rochester (http://www.freebsd.org/cgi/query-pr.cgi?pr=2920)
+        (also http://cvsweb.freebsd.org/ports/graphics/xv/files/patch-af, -ag)
+  JZ  = Joe Zbiciak (http://spatula-city.org/~im14u2c/)

+
+Other credits are as listed on the XV Downloads page or in the respective
+patches (e.g., the jp-extension patches or within the PNG patch).
+
+Finally, please note that these patches have not been blessed by John Bradley
+in any way (although I copied him on the May 2004 announcement--no response
+at that time).  Nor have I personally tested every change and feature!  (See
+the BIG SCARY WARNING below for further caveats.)  In other words, they're
+both completely unofficial and completely unguaranteed.  But they seem to
+work for me.  (And when they don't, I fix 'em.  Eventually, anyway... ;-) )
+
+One further "final" note:  as of this release, I am no longer updating the
+fixes patch; new stuff (including fixes) now appears only in the enhancements
+one.  It simply became too much of a timesink to maintain parallel trees--not
+to mention parallel makefiles (generic/public vs. local/personal, old vs.
+new libjpeg/libtiff) and xv.h (unregistered/public vs. registered/personal),
+particularly when some fixes came about while working on an enhancement and
+others were provided by third parties relative to the previous fix+enh state.
+Hence the mismatched "20050410" date on the fixes patch.

+
+How to build
+------------
+
+The following assumes you, the user, already have the libtiff,[1]
+libjpeg,[2] libpng,[3] and zlib[4] libraries downloaded, patched (if
+necessary), compiled, and installed, not to mention a C compiler and
+the bzip2,[5] tar,[6] patch,[7] and make[8] utilities. You should also
+have downloaded the original XV 3.10a source distribution from the XV
+Downloads page[9] and be able to edit its Makefile and config.h files
+as indicated in the INSTALL file. Finally, you should know what a
+Unix(-style) command line is, where to find one, and how to wield it
+with abandon (or at least with adult supervision)--and preferably not
+as the root user until the make install step.  (A filesystem is a
+terrible thing to waste.)

+|  These patches work for Greg (and parts of them apparently work for     |
+|  various other people), and so far Greg's CPU still computes and his    |
+|  hard disks haven't been wiped.  But there's no guarantee that that     |
+|  will be the case for you! In particular, not every incorporated patch  |
+|  has been explicitly tested, nor has every possible subcase of the      |
+|  explicitly tested subset. (Read that again; it's grammatical.) Nor are |
+|  these patches officially blessed by John Bradley in any way. In other  |
+|  words, if you use these patches, you do so at your own risk. (Greg     |
+|  doesn't believe there are any serious problems remaining, but then,    |
+|  what programmer ever does? Bugs happen.)                               |
+|                                                                         |

+
+Assuming you have the prerequisites out of the way and aren't scared
+off by the Big Scary Warning, here's the build procedure:
+
+      bzip2 -dc xv-3.10a-jumbo-patches-20050501.tar.bz2 | tar xvf -
+      (or tar xvzf xv-3.10a-jumbo-patches-20050501.tar.gz) 
+
+      tar xvzf xv-3.10a.tar.gz 
+
+      cd xv-3.10a 
+
+      patch -p1 < ../xv-3.10a-jumbo-fix-patch-20050410.txt 
+
+      [optional] patch -p1 < ../xv-3.10a-jumbo-enh-patch-20050501.txt 
+
+      edit Makefile and config.h as directed in INSTALL file (in particular,
+      ensure paths to external libraries and header files are correct)
+
+      make 
+
+      ./xv your_favorite_image your_other_favorite_image etc. 
+
+If everything seems to be working to your satisfaction, go ahead and install: 
+
+      make -n install (and double-check that things will be installed
+      where you want them to be)
+
+      become root if necessary (e.g., type su)
+
+      make install 
+
+That wasn't so hard, was it?

+ChangeLog
+---------
+
+  20000220
+    original pair of jumbo patches, comprising perhaps 16 fix-patches and a
+    dozen enhancement-patches; never publicly released 
+
+  20040516
+    first public release, incorporating 25 fix-patches and 21 enhancement-
+    patches
+
+  20040523
+    minor fix to xvctrl.c to support registered versions (GRR warnings-patch
+    was slightly overzealous); switched to tarball packaging
+
+  20040531
+    fixed undefined CLK_TCK with gcc -ansi (enh/USE_TICKS option); made
+    libjpeg, libtiff, libpng and zlib sections of makefile more consistent
+    (enh)
+
+  20040606
+    added freshmeat link, build instructions, and changelog to jumbo README
+    (this file)
+
+  20050213
+    increased max number of files from 4096 to 32768 (enh)
+
+  20050320-20050410
+    fixed two very long-standing YCbCr bugs in TIFF decoder (fix);
+    provisionally fixed bug in TIFF decoder for contiguous tiled TIFFs with
+    bottom-* orientation (fix/USE_TILED_TIFF_BOTLEFT_FIX option); fixed new
+    gcc 3.3 warnings (fix); fixed incorrect 16/24-bit display of xwd dumps
+    (fix); fixed multiple input-validation bugs (potential heap overflows)
+    and mktemp() dependencies (*SECURITY* fixes:  CAN-2004-1725, CAN-2004-
+    1726, CAN-2005-0665, CERT VU#622622, and others); added support for 16-
+    and 32-bit BMPs using bitfields "compression" (enh); fixed probable byte-
+    sex bug in 24-bit FixPix display code (enh/USE_24BIT_ENDIAN_FIX option);
+    fixed numerical-keypad NumLock behavior and delete-key behavior in file-
+    load/save window (enh); made schnauzer window and icons configurable (enh)
+
+  20050417
+    incorporated "Japanese extension" patches, revision 5.3.3 (enh); fixed
+    additional *SECURITY* issues (format-string vulnerabilities, system()
+    and mktemp() calls, etc., but NOT heap overflows in new decoders) both
+    in existing code and in jp-extension additions (enh)
+
+  20050425
+    added support for -startgrab option (enh); added support for a "Never"
+    button to file-overwrite popups (enh); added NetBSD and BSDI to list of
+    mkstemp()-supporting systems (enh); improved line-drawing code to set the
+    correct pixels for lines of all slopes (enh); added "Page n of m" to Info
+    window for multipage images (enh); added support for multipage (animated)
+    GIFs (enh); fixed -random support so randomized file list can be traversed
+    normally in forward or backward direction (enh); added typecasts to stat()
+    printfs for portability (enh); fixed erroneous use of "creation" time and
+    forced unlink prior to overwrite in schnauzer thumbnail code (enh); added
+    HIPS support (enh/HAVE_HIPS option)
+
+  20050501
+    extended multipage keyboard support (PgUp/PgDn) to all windows except
+    control ("console") and directory (enh); fixed minor (non-security)
+    format-string issue in xv.c (enh); shortened delay on popup error windows
+    from 3 seconds to 1 second (enh); tweaked text-viewer localization support
+    (TV_L10N) for Linux (enh); added keyboard short cuts for Color and
+    Grayscale buttons in print dialog (enh); added support for separate "magic
+    suffix" (xv_mgcsfx) config dir (enh); added PREFIX and DESTDIR support to
+    Makefile (enh); fixed handling of zero-length files and other text-viewer
+    failures (enh)

+-I very much doubt that this is an exhaustive list.  So far, most of the other
+-patch-sets appear not to be quite as extensive or as up-to-date as my own,
+-although the last three or four do include the [large] Japanese extension
+-patches that I omitted--not because they're unworthy, but simply because I
+-didn't find them until collisions between the two sets of patches had become
+-a large problem.  (Maybe for the next release...  I'd intended to try for
+-this release, but the security issues ended up taking almost all of my
+-available time.  And, to be honest, from my perspective, inclusion of the
+-jp-extension patches is more for completeness' sake than personal interest,
+-so their priority is fairly low.)

+-have been difficult to accomplish even if I'd had the time.  In any case,

+-care can "subtract" the two sets of patches to see what I did.

+-vs. local/personal, old vs. new libjpeg/libtiff) and xv.h (unregistered/
+-public vs. registered/personal), particularly when some fixes come about
+-while working on an enhancement.  Henceforth--assuming, of course, that
+-there _is_ a "henceforth"--I expect to merge the patches into a single
+-jumbo patch.  (Alternatively, I may simply freeze the current fix-patch
+-and continue to evolve only the enhancements patch; in particular, new
+-fixes would appear only in it.  Either approach would be simple enough;
+-feedback as to which would be preferable is welcomed.)

++
++PCD patch for XV 3.10a Release Notes 2001/07/08.
++
++See also the progress notes at the end of this file. Thanks to all those
++contributors who have substantially improved this patch.
++
++These patches allow xv to read Kodak photocd files and choose which of the
++5 available resolutions one wants to view.
++
++When a photocd file is loaded, a dialog box asks which resolution you
++would like. The visual schnauzer builds thumbnails by reading the lowest
++resolution image. The selected resolution can be selected from the
++command line with the -pcd option:
++
++	[-pcd 0|1|2|3|4]
++
++where:
++
++	0=192*128,	base/16 resolution
++	1=384*256,	base/4 resolution
++	2=768*512,	base resolution
++	3=1536*1024,	4base resolution
++	4=3072*2048	16base resolution.
++
++Note that the Pro format is not supported.
++
++The command line option allows loops without the dialog box popping up, eg.:
++
++	xv -pcd 1 -wloop -wait 10 *.pcd
++
++The code is pretty crude and was written quickly for a specific purpose and
++has not really been cleaned up. It is poorly structured, full of debugging
++codes and verbose comments, and there is very little attempt at optimizing
++things. No profiling has been done.
++
++There is not yet support for overview files, nor is there a facility to
++use the higher resolution chroma planes from when viewing lower resolution
++images.
++
++It's only claim to fame is that it works and produces reasonable looking
++images.
++
++The outline of this is shamelessly derived from xvpbm.c to read the
++file, and xvtiffwr.c to handle the popup window and X stuff (X never
++has been my forte !), and the PhotoCD format information (though not
++the code) was found in Hadmut Danisch's (danisch@ira.uka.de) hpcdtoppm
++program in which he has reverse engineered the format by studying
++hex dumps of PhotoCDs ! The color stuff and Huffman decding were
++extensively revised by Matthew Francey.
++
++Feel free to send me comments or improvements, or even better, more
++information about the photo CD format ... hopefully someone who really
++knows what they are doing will tidy it up or do a neater job.

++
++---------
++
++The trace #define in xvpcd.c is now in the right place, and the ansi
++prototype for the magnify function has been fixed. Colin made me switch to
++xvbcopy() which seems like a good idea for System V victims.

++
++I have done some more work using your patch I thought you might be intested in.
++The major change was adding a size parameter to the LoadPCD; either -1 to mean
++the popup or else the size you desired. This allows batch mode processing,
++specifically xv -pcd <size> <filename>, and the visual schnauzer can work in 
++quick mode (ie. you don't have to select each image size when it is building 
++the icons)
++
++I have added an xbm file for the file type but haven't drawn an icon for it,
++this is in bitmaps/br_pcd.xbm. I will just send you the new files.

++
++This is David Clunie's patch for xv-3.00 tuned a bit to work
++on xv-3.10. The code's all the same except for replacing 
++"trace" with "fprintf" in xvpcd.c and adding an "unsigned" qualifier to 
++keep my compiler (gcc) happy. Oh yes, changed RFT_PCD to 20 as
++John Bradley has now used 15 through 19.

++
++Andrew's patch didn't include Colin's browser changes, so I redid the
++xv-3.10 update from scratch ... it seems pretty much the same as
++Andrew's changes. I also edited the Imakefile and Makefiles in order
++to support the PCD changes, as well as make the install process a
++little more flexible, with options to strip and set modes and so on.
++Also made RFT_PCD 25 so as not to conflict with magpic patch from Japan
++by Ikemoto Masahiro <ikeyan@airlab.cs.ritsumei.ac.jp>, and used his
++bitmap icon for pcd files.
++
++Now there are two versions of the patch, one which should be applied
++to the xv-3.10 distribution.
++
++The other should be applied to xv-3.10 AFTER Ikemoto Masahiro's 
++Patch.magpic2.PhotoCD.XV319a, in order to add the browser features to
++the latter, as well as fixing a Makefile typo (was xcpcd.c not xvpcd.c)
++and including unistd.h for the SEEK_xxx constants in the magicpic
++stuff.

++Subject: Re: photo-cd patch for xv 
++From: Matthew Francey <mdf@angoss.com>
++Date: Mon, 26 Mar 2001 15:37:55 +0000
++
++Attached is a revised version of xvpcd.c;  the areas that I have
++re-written or changed are in a different coding style so you can tell
++what has changed.  The GNU 'indent' program can be run against the file
++to enforce a consistent style ..
++
++Here is what I've done though:
++
++a) huffman table reader re-written, because it would fail on some
++   photocd files with "unusual" huffman codes.
++
++b) the huffman-coded corrections are now properly applied
++
++c) the corrections can sometimes over or underflow;  clipping has been
++   introduced and effectively fixes the problem, but I suspect that
++   there is something deeper going on.
++
++d) the "official" YCC->sRGB transform is done.  a "beyond 100% white"
++   mapping table was snarfed from ImageMagick.  an option for using a
++   flat linear LUT was added -- this can make somewhat over-exposed images
++   look alot nicer.
++
++e) there were strange problems where the code wouldn't be able to find
++   the huffman tables and data for the 16base image (the bit-buffering
++   code was starting mid-sector, instead of at a sector boundary).  Looking
++   at a pcd file with a hex editor suggests to me that it is possible to
++   just skip directly to these huffman tables -- no special "+12" and such
++   constants necessary.  But I haven't tried this yet.
++
++The results:  I've been able to read about 50 or 60 .pcd files [scattered
++in age from 6 years old to scans done last week] with this code without
++incident.  Image quality at the high resolution is excellent.  Even the
++trivial amount of LUT control is useful when dealing with over-exposed
++images.
++
++If I get around to it:  finer LUT control to take advantage of the
++slightly extended dynamic range of PhotoCD scans, especially in regards to
++dark or somewhat underexposed scenes.

++ * Features
++ * ========
++ * Use the filters as input and output method for load and save unsupported
++ * image format file. The filter command is recognized by definition of
++ * magic number or suffix in "~/.xv_mgcsfx" .
++ *
++ * Bugs
++ * ====
++ * There are many bugs.
++ * Let's go hunting for insects with an insect net. (it's all joke.)

++ * What is this?
++ *
++ *  It is a package to show multi-lingual text.
++ *
++ * How to use?
++ *
++ *  1. Call ml_set_screen(Screen *scr);
++ *	Tell this package the screen you use.
++ *
++ *  2. Call ml_set_charsets(struct char_spec spec[4], int gl, int gr);
++ *	Tell this package the initial charsets.
++ *	Gn is set to the charset specified by spec[n], respectively.
++ *	GL and GR are set to G[gl] and G[gr], respectively.
++ *	If first call, iso8859-1 font is loaded.
++ *
++ *  3. Call ml_draw_text(char *string);
++ *	It Creates a bitmap, and returns it to you.
++ *	If something goes wrong, it returns None.
++ *	DON'T free the returned pixmaps!!
++ *
++ * BUGS:
++ *  - Amharic and Tigrigna characters are strange.
++ *  - Big5 is not supported.
++ *  - Reverse direction is not supported.
++ *  - Composing is not supported.
++ *  - Cantonese can't be shown.
++ *  - Texts which have many lines are buggy.
++ *
++ * NOTE:
++ *  - Shifted JIS and Shifted GB must be converted to iso2022 in advance.
++ *
++ * Example of parameters to ml_set_charsets:
++ *  - EUC-Japan
++ *	spec = { {1, 94, 'B'},		G0 is US-ASCII
++ *		 {2, 94, 'B'},		G1 is JIS X0208
++ *		 {1, 94, 'J'},		G2 is (right-half of)JIS X0201
++ *		 {2, 94, 'D'} };	G3 is JIS X0212
++ *	gl = 0;				GL is G0
++ *	gr = 1;				GR is G1
++ *
++ *  - Compound Text
++ *	spec = { {1, 94, 'B'},		G0 is US-ASCII
++ *		 {1, 96, 'A'},		G1 is Latin-1
++ *		 {1, 94, 'B'},		G2 is US-ASCII (maybe unused)
++ *		 {1, 94, 'B'} };	G3 is US-ASCII (maybe unused)
++ *	gl = 0;				GL is G0
++ *	gr = 1;				GR is G1
++ *
++ *  - Korean Mail
++ *	spec = { {1, 94, 'B'},		G0 is US-ASCII
++ *		 {2, 94, 'C'},		G1 is KSC5601
++ *		 {1, 94, 'B'},		G2 is US-ASCII (maybe unused)
++ *		 {1, 94, 'B'} };	G3 is US-ASCII (maybe unused)

++ * $Id: xvpic2.c,v 2.9.1.14 1995/04/24 15:34:15 ikeyan Exp $
++ * xvpic2.c - load and save routines for `PIC2' format pictures.
++ *
++ *
++ * Outline
++ * =======
++ * xvpic2.c supports the PIC2 format image file. It is used some
++ * Japanese personal computer users.
++ *
++ * The PIC2 format is designed by A.Yanagisawa. It is an excellent
++ * format except for its encode/decode speed. ;-)
++ *
++ * The features of the PIC2 format:
++ * - Powerful header information (included author, filename, title,
++ *   saver, product number, created date and comment).
++ * - Reversible compression, and very high compression ratio (in many
++ *   cases, a higher compression ratio than the JPEG compression;
++ *   because of its compression method, PIC2 is especially good at
++ *   pictures like cell animation).
++ * - Can handle full-color (24 bits) image.
++ * - Can include multi image blocks into one PIC2 file.
++ * - Have four different block format (P2SS, P2SF, P2BM and
++ *   P2BI). P2SS format uses arithmetic compression for storing
++ *   data. P2SF uses normal run-length compression. P2BM and P2BI is
++ *   raw image format. Select any one according to the situation.
++ *
++ * Explanation of the PIC2 compression:
++
++ * - In the first place, try to record pixel color, uses color caches
++ *   which keep some recent colors, and formed according to color's
++ *   frequency.  PIC2 has some color cache spaces that are switched by
++ *   upper pixel value of current pixel.  If cache is hit, record
++ *   that.
++ * - Unfortunately, in the case of color cache didn't hit, record the
++ *   difference from the value estimated with the value of upper and
++ *   left pixel of current pixel (similar to PNG's AVG predictor).
++ * - And extract image's color chain if exist, and record that (it
++ *   results in image's outline).
++ * - In all cases, arithmetic compression is used in the final stage
++ *   before writing the file, which in theory produces the ideal
++ *   compression ratio (P2SS).
++ *
++ * Features
++ * ========
++ * - Support 3,6,9,12,15,18,21,24bit PIC2 format (Load/Save).
++ * - Support all image block formats of PIC2 (Load/Save).
++ * - Support multi block PIC2 file (Load/Save).
++ *
++ *
++ * Bugs
++ * ====
++ * - Unsupport 8bit PIC2 image file.
++ *
++ * If you find other bugs (surely exist :-)), send me bug-report.
++ *

++These are the latest versions of the XV jumbo patches I originally created
++in February 2000 (but never distributed) and eventually updated and released
++in May 2004, prompted by a discussion on LWN (http://lwn.net/Articles/76391/).
++Information about the patches, updates to the patches, and the patches
++themselves can all be found here:
++
++	http://pobox.com/~newt/greg_xv.html
++	http://freshmeat.net/projects/xvjumbopatches/
++
++(Use the "Subscribe to new releases" link on the latter page if you want to
++be notified of new versions automatically; trivial registration required.)
++
++These two patches incorporate all of the fix- and enhancement-patches
++available from John's XV site (http://www.trilon.com/xv/downloads.html
++and ftp://ftp.trilon.com/pub/xv/patches/), plus a number of my own fixes
++and additions, plus quite a few from other people--though not all of the
++ones I'd intended to (sorry, SJT, AT, and JPD!) due to lack of time after
++dealing with the latest security issue (which I discovered, sigh).  They're
++still not fully complete, and it's possible they never will be, but I do
++plan to continue working on them whenever the mood strikes--and I may even
++release them publicly on rare occasions.  (At the current rate, it looks
++like once a year may be the best we can hope for...we'll see.)
++
++Also be aware that several other people have had the same idea over the
++years.  Ones I've found, more or less by accident, include:

++I very much doubt that this is an exhaustive list.  So far, most of the other
++patch-sets appear not to be quite as extensive or as up-to-date as my own,
++although the last three or four do include the [large] Japanese extension
++patches that I omitted--not because they're unworthy, but simply because I
++didn't find them until collisions between the two sets of patches had become
++a large problem.  (Maybe for the next release...  I'd intended to try for
++this release, but the security issues ended up taking almost all of my
++available time.  And, to be honest, from my perspective, inclusion of the
++jp-extension patches is more for completeness' sake than personal interest,
++so their priority is fairly low.)
++
++Below I summarize the component patches that are encompassed by my jumbo
++bugfixes and jumbo enhancements patches.  Unfortunately, some of my own
++additions never saw the light of day as standalone patches, but considering
++the number of overlaps (collisions) already implicit in this list, it would
++have been difficult to accomplish even if I'd had the time.  In any case,
++they're present in these jumbo patches but not chongo's, so those who _really_
++care can "subtract" the two sets of patches to see what I did.
++
++Here's a quick guide to the "third-party" credits in the lists below:

++  AT  = Anthony Thyssen (http://www.cit.gu.edu.au/~anthony/)
++  DAC = David A. Clunie (http://www.dclunie.com/xv-pcd.html)
++  EK  = Egmont Koblinger (egmont@users.sourceforge.net)

++  JHB = John H. Bradley, of course (http://www.trilon.com/xv/)
++  JPD = Jean-Pierre Demailly (http://www-fourier.ujf-grenoble.fr/~demailly/)
++  JR  = John Rochester (http://www.freebsd.org/cgi/query-pr.cgi?pr=2920)

++
++Other credits are as listed on the XV Downloads page or in the respective
++patches (e.g., the jp-extension patches or within the PNG patch).
++
++Finally, please note that these patches have not been blessed by John Bradley
++in any way (although I copied him on the May 2004 announcement--no response).
++Nor have I personally tested every change and feature!  (See the BIG SCARY
++WARNING below for further caveats.)  In other words, they're both completely
++unofficial and completely unguaranteed.  But they seem to work for me.  (And
++when they don't, I fix 'em.  Eventually, anyway... ;-) )
++
++One further "final" note:  this may well be the last release to include
++separate fix- and enhancements-patches.  It is too much of a timesink to
++maintain parallel trees--not to mention parallel makefiles (generic/public
++vs. local/personal, old vs. new libjpeg/libtiff) and xv.h (unregistered/
++public vs. registered/personal), particularly when some fixes come about
++while working on an enhancement.  Henceforth--assuming, of course, that
++there _is_ a "henceforth"--I expect to merge the patches into a single
++jumbo patch.  (Alternatively, I may simply freeze the current fix-patch
++and continue to evolve only the enhancements patch; in particular, new
++fixes would appear only in it.  Either approach would be simple enough;
++feedback as to which would be preferable is welcomed.)

++How to build
++------------
++
++The following assumes you, the user, already have the libtiff,[1]
++libjpeg,[2] libpng,[3] and zlib[4] libraries downloaded, patched (if
++necessary), compiled, and installed, not to mention a C compiler and
++the bzip2,[5] tar,[6] patch,[7] and make[8] utilities. You should also
++have downloaded the original XV 3.10a source distribution from the XV
++Downloads page[9] and be able to edit its Makefile and config.h files
++as indicated in the INSTALL file. Finally, you should know what a
++Unix(-style) command line is, where to find one, and how to wield it
++with abandon (or at least with adult supervision)--and preferably not
++as the root user until the make install step.  (A filesystem is a
++terrible thing to waste.)

++Assuming you have the prerequisites out of the way and aren't scared
++off by the Big Scary Warning, here's the build procedure:
++
++      bzip2 -dc xv-3.10a-jumbo-patches-20050410.tar.bz2 | tar xvf -
++      (or tar xvzf xv-3.10a-jumbo-patches-20050410.tar.gz) 
++
++      tar xvzf xv-3.10a.tar.gz 
++

++
++      [optional] patch -p1 < ../xv-3.10a-jumbo-enh-patch-20050410.txt 
++
++      edit Makefile and config.h as directed in INSTALL file (in particular,
++      ensure paths to external libraries and header files are correct)
++
++      make 
++
++      ./xv your_favorite_image your_other_favorite_image etc. 
++
++If everything seems to be working to your satisfaction, go ahead and install: 
++
++      make -n install (and double-check that things will be installed
++      where you want them to be)
++
++      become root if necessary (e.g., type su)
++
++      make install 
++
++That wasn't so hard, was it?

++    patches
++
++  20040523

++
++  20040531
++    fixed undefined CLK_TCK with gcc -ansi (enh/USE_TICKS option); made
++    libjpeg, libtiff, libpng and zlib sections of makefile more consistent

++    added freshmeat link, build instructions, and changelog to jumbo README
++    (this file)
++
++  20050213
++    increased max number of files from 4096 to 32768 (enh)
++
++  20050320-20050410
++    fixed two very long-standing YCbCr bugs in TIFF decoder (fix);
++    provisionally fixed bug in TIFF decoder for contiguous tiled TIFFs with
++    bottom-* orientation (fix/USE_TILED_TIFF_BOTLEFT_FIX option); fixed new
++    gcc 3.3 warnings (fix); fixed incorrect 16/24-bit display of xwd dumps
++    (fix); fixed multiple input-validation bugs (potential heap overflows)
++    and mktemp() dependencies (*SECURITY* fixes:  CAN-2004-1725, CAN-2004-
++    1726, CAN-2005-0665, CERT VU#622622, and others); added support for 16-
++    and 32-bit BMPs using bitfields "compression" (enh); fixed probable byte-
++    sex bug in 24-bit FixPix display code (enh/USE_24BIT_ENDIAN_FIX option);
++    fixed numerical-keypad NumLock behavior and delete-key behavior in file-
++    load/save window (enh); made schnauzer window and icons configurable (enh)

+Installation Instructions:
+
+This patch will update XV 3.10 to 3.10a.
+
+Copy this file into the top-level XV source directory, and apply it using:
+   patch -p0 <xv-3.10a.patch
+
+Then do a 'make clean', followed by a 'make' (or 'make install').
+
+Note:  if you don't have a copy of the 'patch' utility, you can get one
+       via anonymous ftp on ftp.cis.upenn.edu, in pub/xv.  Of course,
+       once you're there, it may be easier to just pick up the latest copy
+       of the XV distribution, rather than try to patch your existing copy,
+       but hey, that's up to you...

+  
+! XV 3.10a bug-fix release  12/29/94
+! ----------------------------------
+! Bug Fix:  Problems loading JPEG files in 8-bit mode on some systems.
+! 				(Rick Richardson (rick@digibd.com))
+! 				(Chad R. Larson  (chad@anasazi.com))
+  
++ Bug Fix:  Added '-pkludge' command line option and 'popupKludge' boolean 
++ 	resource.  If true, selects the 'old-style' pop-up window positioning
++ 	code.  The various popup windows should appear with the Ok button
++ 	(or whatever) centered around the cursor.  If the windows routinely
++ 	pop up slightly off-center from the cursor, try turning this on.
+  
+! Bug Fix:  '3' and 'Q' characters in the Text Annotation character set were
+! 	boogered up...		(Sidik Isani (si@acpub.duke.edu))
+! 
+! Bug Fix:  '-iconic' option wasn't working.
+! 				(David Pesetsky  (iedsp@agt.gmeds.com))
+! 
+! Bug Fix:  Didn't properly read greyscale RLE files.
+! 				(Robert Cunningham  (rkc@xn.ll.mit.edu))
+! 
+! Bug Fix:  'AutoCrop' on 24-bit images could produce 0x0 images.  A problem!
+! 				(Leon Shaner  (leon@mtu.edu))
+! 
+! Bug Fix:  GIF reader would blow up if there were multiple comments.
+! 				(Markus Gyger  (mgyger@itr.ch))
+! 
+! Bug Fix:  Behavior under virtual window managers may be improved.
+! 				(steveg@pa.dec.com)
+! 
+! Enhancement:  Text in 'temperature gauge' (during slow operations) is now
+! 	XOR'd on, so it isn't obscured by the filled area of the gauge.

++ \fIvdcomp\fP - decompress a compressed PDS image
++ .SH Synopsis
++ \fIvdcomp\fP [ infile ] [ outfile ] [ format-code ]
++ .SH Description
++ The \fIvdcomp\fP program reads a variable length compressed PDS image
++ and outputs a fixed length uncompressed image file in PDS format with
++ labels, image histogram, engineering table, line header table and an
++ image with PDS, FITS, VICAR or no labels.
++ .PP
++ If used on a non-byte-swapped machine the image histogram is
++ un-swapped.
++ .SH Options
++ \fIVdcomp\fP will prompt for any options that are not supplied on the
++ command-line.
++ .PP
++ \fIinfile\fP
++ .br
++ .RS
++ The name of compressed image file.
++ .RE
++ .PP
++ \fIoutfile\fP
++ .br
++ .RS
++ The name of uncompressed image file.
++ .RE
++ .PP
++ \fIformat-code\fP
++ .br

++ Select from the following list:
++ .br
++ .RS
++ \fI1\fP - SFDU/PDS format [default]
++ .br
++ \fI2\fP - FITS format
++ .br
++ \fI3\fP - VICAR format
++ .br
++ \fI4\fP - unlabelled binary array
++ .RE

++ .SH Limitations
++ This program has been tested on a VAX 780 (VMS 4.6), SUN Workstation
++ (UNIX 4.2, release 3.4), an IBM PC (MICROSOFT 5.1 compiler) and
++ Macintosh IIx using Lightspeed C version 3.0.  When converting to
++ other systems, check for portability conflicts.
++ .SH Credits
++ This program uses Kris Becker's subroutine DECOMP.C (which is included
++ in this program in a shortened version).
++ .SH History
++ bradley@cis.upenn.edu 06-23-94 ansi-fied program
++ .PP
++ datri@convex.com, 11-15-91 added recognition of - as stdout for output
++ filename; disabled various messages; directed messages to stderr;

++ They said it couldn't be done.  They said it never *would* be done.  
++ They smiled knowingly to themselves as each predicted release date 
++ inevitably passed by, unmarked by the emergence of a new version...
++ 
++ Well, who asked them!  And who do they think they are, anyhow!?!
++ 
++ Announcing the Exciting New Release of XV, Version 3.10!
++ 
++ Finally, all the stuff you've been waiting for:  image cut & paste, pixel
++ editing, text annotation (of a sort), nifty new algorithms, new image formats 
++ (Targa, XPM, FITS, XWD, IFF), improved schnauzing capabilities, a spiffy
++ new 'pad' command, and whatnot.  Plenty of whatnot.

++ Of course, we're particularly proud of our Exclusive 3-D Fish Technology.
