+This patch contains the following bugfixes:
+
+* the TIMEOUT (and -t flag) has now different effect for getty and uugetty:
+  with uugetty, TIMEOUT set will now cause uugetty exit no matter whether
+  there has been any input from the user (the counting will start immediately
+  after login() has been spawned - pre- getty-2.1.0 behavior), while for
+  getty, it will make the counter start after single input has been detected
+  from the user
+  * getty.1 manpage updated accordingly
+
+* @F issue substitution now works as expected
+
+* @V / VERSION functionality documentation fix in getty.1 manpage
+
+* fixed a bunch of memleaks (if not all):
+  * Fputs() made strdup()-free (we now use static structs where possible)
+  * avoided unnecessary dual strdup() for Version in defs()
+  * freeing of "DEF **def" including its internals is now handled, as well as
+    feeing of other variables in defs() pointing to strdup()ed memory areas

+Title: 		getty-ps
+Version: 	2.1.0
+Entered-date: 	27SEP02
+Description:	A versatile getty/uugetty program designed to allow easy
+		use of a modem for incoming/outgoing data/fax/voice calls.
+		It also allows easy set-up of regular login ports.  Unlike
+		agetty, it stores most of it's configuration and port
+		initialization information in up to 2 files.  This usually
+		results in slightly more involved initial installation, but
+		easier	maintenance than agetty.  It also leaves the
+		inittab entries looking uncluttered.  Supports 57600 and
+		faster speeds, and is compatible with uucp and efax-0.9[a].
+		Ringback is provided as an optional feature.
+Keywords:	getty uugetty serial modem ringback efax uucp
+Author:		Paul Sutcliffe, Jr.

+Alternate-site:	ftp.nwmagic.net:/pub/sources/getty_ps-2.1.0.tar.gz
+Original-site:	Unknown
+Platforms: 	Linux (tested on 1.0.x-2.4.5, Slackware 4.0 thru 8.1); should
+		compile and work on almost any Unix, after library
+		compatibility is resolved and paths are checked in tune.h;
+		compiles clean with gcc 2.7.2.3 & 2.95.3.

+# 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 ':'.

+This is the latest version 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 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 (security-related and otherwise), plus quite a few from other
+people.  They're still not fully complete, and it's probable 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, once every few years may be the best we can hope for....)
+
+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:

+
+This is not an exhaustive list (e.g., Jörgen Grahn also had one).  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, circa 2005.  (As of 2007, they're
+distributed as a single monster-patch, and the "component patches" are now
+listed in the changelog section at the bottom of this file.)  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 the
+list, that 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 and changelog

+(Daniel Kirchheimer, 5 Dec 2005).  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 try to fix 'em--eventually,
+anyway... ;-) )

+How to build
+------------
+
+The following assumes you, the user, already have the libtiff,[1] libjpeg,[2]
+libpng,[3] zlib,[4] and JasPer[5] libraries downloaded, patched (if necessary),
+compiled, and installed, not to mention a C compiler and the bzip2,[6] tar,[7]
+patch,[8] and make[9] utilities.  You should also have downloaded the original
+XV 3.10a source distribution from the XV Downloads page[10] and be able to edit
+its Makefile and config.h files as indicated in the INSTALL file.  (Editing
+the Makefile will also allow you to disable some of the third-party libraries
+if you wish.)  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 reportedly 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 this     |
+|  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:
+
+      tar xvzf xv-3.10a-jumbo-patches-20070520.tar.gz
+      (or:  gzip -dc xv-3.10a-jumbo-patches-20070520.tar.gz | tar xvf - )
+
+      tar xvzf xv-3.10a.tar.gz 
+
+      cd xv-3.10a 
+
+      patch -p1 < ../xv-3.10a-jumbo-fix-enh-patch-20070520.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 
+      (or:  sudo 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-

++This is the latest version 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 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 (security-related and otherwise), plus quite a few from other
++people.  They're still not fully complete, and it's probable 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, once every few years may be the best we can hope for....)
++
++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:

++
++This is not an exhaustive list (e.g., Jörgen Grahn also had one).  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, circa 2005.  (As of 2007, they're
++distributed as a single monster-patch, and the "component patches" are now
++listed in the changelog section at the bottom of this file.)  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 the
++list, that 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 and changelog

++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 and wrote to
++him again in May 2005), unless you count Debian's redistribution permission
++(Daniel Kirchheimer, 5 Dec 2005).  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 try to fix 'em--eventually,
++anyway... ;-) )

++How to build
++------------
++
++The following assumes you, the user, already have the libtiff,[1] libjpeg,[2]
++libpng,[3] zlib,[4] and JasPer[5] libraries downloaded, patched (if necessary),
++compiled, and installed, not to mention a C compiler and the bzip2,[6] tar,[7]
++patch,[8] and make[9] utilities.  You should also have downloaded the original
++XV 3.10a source distribution from the XV Downloads page[10] and be able to edit
++its Makefile and config.h files as indicated in the INSTALL file.  (Editing
++the Makefile will also allow you to disable some of the third-party libraries
++if you wish.)  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:
++
++      tar xvzf xv-3.10a-jumbo-patches-20070520.tar.gz
++      (or:  gzip -dc xv-3.10a-jumbo-patches-20070520.tar.gz | tar xvf - )
++
++      tar xvzf xv-3.10a.tar.gz 
++
++      cd xv-3.10a 
++
++      patch -p1 < ../xv-3.10a-jumbo-fix-enh-patch-20070520.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 
++      (or:  sudo make install)
++
++That wasn't so hard, was it?

++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.
++

++Greg,
++     After winding up in dark lonely places trying to
++get xv-3.10a to build on FC5 I suspected I was missing
++something.  Then I happened on your patch manifest
++in Slackware 10.2.
++
++I bandsawed the script a bit to use in propagating XV
++to a handful of personal FC5 machines.  Attached for
++reference.
++
++Thanks for your effort!

++-- License and Disclaimer --
++
++This patch & script package was written by Alexey Spiridonov, and is
++licensed under the GNU GPLv2. There is NO WARRANTY.
++
++XV is copyrighted by John Bradley.
++
++-- What is this? --
++
++This is a small patch for XV that allows you to run scripts by pressing 
++a key from F1 through F12 (or more, just change 12 to your number in the
++patch file). 
++
++The patch enables a number of useful features. Here is a my set-up:
++
++F1: Losslessly rotate JPEG 90 degrees to the right.
++F2: Losslessly rotate JPEG 90 degrees to the left.
++
++F3: Print the current selection rectangle (on the terminal where xv was 
++    launched). This is useful for quickly recording a bunch of positions in
++    an image. Use case: 
++      I'm annotating face positions.
++        1) Select Joe in picture, hit F3, type "Joe" in the terminal.
++        2) Select Jane in the picture, ... 
++        ...
++        n) Copy the text visible in the terminal, and paste it into the
++           JPEG comment.
++    Of course, i would write a more convenient script if I annotated faces 
++    with any any frequency.
++
++F4: Edit JPEG comment (I use it for annotations/tags).
++
++F5: Log a 'losslessly rotate right' command for batch processing.  This
++    writes the rotation command for the current file into a shell script
++    somewhere ("~/photos/bin/rotscript" by default). This is great for 
++    slower computers because you don't have to wait for each image to 
++    rotate; instead, you just rotate them all at once by running the 
++    resulting script.
++F6: Log a 'losslessly rotate left' batch command.
++
++F8: Crop image on disk, but back-up the uncropped version. You can make 
++    a succession of crops this way, with a backup made at every step.
++    This wastes disk space, so be sure to clean up once you get a crop you
++    like.
++F7: Undo the last crop done on this image. This can be repeated until you're
++    back at the original.
++
++-- Installation --
++
++I'll tell you how to get the set-up I described above. Of course, you can
++customize it to your heart's content.
++
++(( 1 ))
++
++Go to:
++
++  http://www.sonic.net/~roelofs/greg_xv.html
++
++and follow the XV install instructions there. If you are okay with
++reading shell scripts, you might also give this a shot:
++
++  http://sources.gentoo.org/viewcvs.py/*checkout*/gentoo-x86/media-gfx/xv/xv-3.10a-r12.ebuild
++
++When you're ready to type "make install", do the following to apply my patch:
++
++  $ cd WHEREVER_YOU_COMPILED_XV
++  $ patch -p1 --dry-run < PATH/TO/xv-3.10a-fkey-command-patch.greg-xv
++
++Hopefully, the above command won't complain; if it does, Greg Roelofs
++probably changed his patchset, and my patch has become out of date -- let me
++know. If that went well, run:
++
++  $ patch -p1 < PATH/TO/xv-3.10a-fkey-command-patch.greg-xv
++  
++Now, simply recompile and install as described in the other instructions.
++  
++(( 2 ))
++
++Copy 'jpegcrop.sh', 'jpegeditcom.sh', 'jpegundocrop.sh', 'jpegrot.sh',
++'jpeglogrot.sh' to some convenient directory.
++
++Suggestions: ~/photos/bin, /usr/local/bin, etc...
++
++Edit 'jpeglogrot.sh' and 'jpegeditcom.sh'. In the former, you need to
++customize the path to 'jpegrot.sh'. In the latter, you should make set 
++your favorite editor. The spots to customize are marked as such.
++
++(( 3 ))
++
++Open .Xdefaults in your favorite text editor, and paste the following lines
++there:
++
++xv.F1command: ~/photos/bin/jpegrot.sh 90 %s
++xv.F2command: ~/photos/bin/jpegrot.sh 270 %s
++xv.F3command: @echo "The selection rect for '%s' is at (%d, %d) of size %dx%d."
++xv.F4command: @~/photos/bin/jpegeditcom.sh %s &
++xv.F5command: @~/photos/bin/jpeglogrot.sh 90 %s
++xv.F6command: @~/photos/bin/jpeglogrot.sh 270 %s
++xv.F7command: ~/photos/bin/jpegundocrop.sh %s
++xv.F8command: ~/photos/bin/jpegcrop.sh %s %d %d %d %d
++
++Change '~/photos/bin/' to the directory you chose in (( 2 )). In case you're
++wondering what the '@' symbol means, it tells XV not to reload the file
++after running this command. The default is to reload the file.
++
++-- Apologies --
++
++I didn't get a chance to run through the above instructions and check
++that they work. I know they're right in spirit, but I might've made a typo
++or two. Even if it's obvious to you, would you please let me know by writing
++to lesha at mit dot edu?

++ * xvjp2k.c - I/O subroutines for JPEG 2000 format pictures
++ *
++ * This module is a "shim" between XV and a JPEG 2000 CODEC in the open-source
++ * JasPer Library created by Michael D. Adams; for more information, see the URL
++ * "http://www.ece.uvic.ca/~mdadams/jasper".  We don't use most of the other
++ * facilities in this library, so it's better to link XV with a UNIX "archive"
++ * representation of it, not a DLL.
++ *
++ * JPEG 2000 files can be represented in either of two general ways:  The
++ * simplest representation is a "code stream", which often has a ".jpc" file
++ * name suffix and is organized much like a classical JPEG file, except that
++ * unfortunately, JPEG 2000 code streams indicate the no. of colors in an image
++ * but no longer give any clues about its color space (e.g., RGB or YCbCr).
++ * Instead, there is now a semantically higher-level representation, which often
++ * has a ".jp2" file name suffix and encapsulates a "code stream" with (possibly
++ * a lot of) color-space information, optionally including things like ICC
++ * correction tables.
++ *
++ * Compared to the IJG JPEG Library used in file "xvjpeg.c", one must solve
++ * several problems for color images when marrying JasPer to XV.
++ *
++ * 1. JPEG 2000 files can represent a wide range of image sizes, resolutions,
++ *    and color spaces, not all of which can be easily rendered "as is" on a
++ * normal "X Windows" display, so we must carefully check a decoded image's
++ * parameters in order to reject anything that we can't handle gracefully.
++ *
++ * 2. JasPer prefers to decode/encode images using color-plane "slices", instead
++ *    of interleaved pixels needed by "X Windows", so we must (de)interleave
++ * copies of the image buffer here.
++ *
++ * XXX  Things to do:
++ *
++ * 1. In "LoadJP{2,C}()" try to handle the "quick" option, which requests
++ *    faster loading of a reduced-size image for the visual schnauzer.  The
++ * schnauzer's icon size is currently 80x60, so the old "xvjpeg.c" module tries
++ * to produce a 2X (160x120) image.  Can we do the same?
++ *
++ * 2. In "StoreJP2K()", JasPer Library Version 1.701 apparently has no API to
++ *    let the XV global "picComments" string be inserted in a JPEG 2000 comment
++ * record.  If the library ever gets fixed, enhance our code accordingly.
++ *
++ * --Scott Marovich <marovich@hpl.hp.com>, Hewlett-Packard Laboratories,

++/* The following variables and subroutines are used when writing a JPEG 2000
++   file, which is done mainly using call-backs from "X Windows" widgets.  The
++   most complicated part of this interface is: managing interactions with a
++   window to request the boat-loads of options that the JasPer Library supports.
++   Start by defining subwindow sizes, plus indices into several arrays of
++   corresponding widget-state variables.
++
++   IMPLEMENTATION NOTES:  The following dimensions create a tall, thin window
++                          which appears to have considerable empty space at the
++   bottom.  Before you complain, click the Precinct Height menu button in order
++   to the tall pop-up subwindow that it generates.  If the parent window is made
++   shorter, then this pop-up will be clipped, which is an ugly nuisance.  I
++   don't know how to make the pop-up visible outside its parent's borders; do
++   you?  If there's some way to make "X Windows" do this, then we might consider
++   making the parent shorter.
++
++   Note that there is currently no mechanism to program the no. of intermediate
++   layers used by the encoder, or their rates.  This is potentially a large and
++   complicated data-entry problem, and perhaps someday we can invent a clever
++   solution using the rest of the parent window's space.

++ * 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

++ * xvpcd.c - load routine for 'PhotoCD' format pictures
++ *
++ * LoadPCD(fname, pinfo, size)  -  loads a PhotoCD file
++ *
++ * This routine will popup a choice of which of the 5 available resolutions
++ * the user wants to choose, then load it as a 24 bit image.
++ *
++ * Copyright 1993 David Clunie, Melbourne, Australia.
++ *
++ * 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 ! After all who can afford the Kodak developer's
++ * kit, which none of us have seen yet ? Am I even allowed to mention these
++ * words (Kodak, PhotoCD) ? I presume they are registered trade marks.
++ *
++ * PS. I have no idea how Halmut worked out the YCC <-> RGB conversion
++ * factors, but I have calculated them from his tables and the results
++ * look good enough to me.
++ *
++ * Added size parameter to allow the schnautzer to create thumnails
++ * without requesting the size every time.

++ * 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.
++ *

++ *		...	(here)	7/16
++ *		3/16	5/16	1/16
++ * We work left-to-right on even rows, right-to-left on odd rows.
++ *
++ * We can get away with a single array (holding one row's worth of errors)
++ * by using it to store the current row's errors at pixel columns not yet
++ * processed, but the next row's errors at columns already processed.  We
++ * need only a few extra variables to hold the errors immediately around the
++ * current column.  (If we are lucky, those variables are in registers, but
++ * even if not, they're probably cheaper to access than array elements are.)

+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.
+! 				(Jerry Whelan  (jerryw@bnl.gov))
+! 
+! Enhancement:  man page for vdcomp written
+! 				(James Ralston Crawford  (qralston+@pitt.edu))
+! 
+! Enhancement:  PCX code can now read 24-bit PCX files.
+! 				(Dave Cohrs  (cohrs@legato.com))
+! 
+! Portability:  Patch for Linux	(David Hankins  (dhankins@oz.net))
+! 
+! Portability:  Patches for ISC 4.0 Interactive/SunSoft Unix
+! 				(Jack Bailey  (jjb@jagware.bcc.com))
+! 
+! Portability:  Compiler noise (from Sun's Professional C compiler) cleaned up.
+! 				(John Fritz  (jfritz@bpo-ess.ceco.com))
+! 
+! Portability:  Many nits picked by Pyramid compiler
+! 				(Chad R. Larson  (chad@anasazi.com))
+! 
+! Portability:  Some malloc's in xvfits.c needed casting.
+! 				(Bill Silvert  (sysop@biome.bio.ns.ca))
+! 
+! Portability:  Further VMS problems solved.
+! 				(Rick Dyson (dyson@sunfish.physics.uiowa.edu))
+! 
+! Portability:  select() on HP-UX 9.x expects (int *) instead of (fd_set *)
+! 				(Richard Allen  (ra@os.is))
+! 
+! Portability:  Removed 'const' from second parameter in decl. for decode_run()
+! 	in tif_fax3.c.		(Glenn Spargo  (gspargo@ctron.com))
+! 
+! Portability:  Added 'fcntl.h' to xv.h, as some systems may not have O_RDONLY
+! 	declared elsewhere.	(Mitchell Blank  (blankm@cae.wisc.edu))
+! 
+! Portability:  Font selection strings in xv.c didn't have enough '*'s in them.
+! 	Would fail on some X servers.
+! 				(Rick Richardson  (rick@digibd.com))
+! 
+! Second XV 3.10 Public Release  12/22/94
+! ----------------------------------------
+! Bug Fix:  Make_xv.com in vms directory wouldn't build xvxpm.c or xvfits.c 
+! 	(and thus, XV!)		(Rick Dyson  (dyson@sunfish.Physics.UIowa.Edu))
+! 
+! 
+! Initial XV 3.10 Public Release  12/21/94

+      SETUP.COM
+          A simple  command  procedure  to  setup  the  final  compiled XV

+!         FERMILAB version).  If it  is  kept in the same directory as the
+!         binaries, it will be able to  get  the  necessary  symbols setup
+!         anywhere the directory structure is located WITHOUT  the need to

++ .SH Name
++ \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
++ .RS
++ 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
++ .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;
++ added exit status
++ .PP
++ DEC89 Modified program to handle both Voyager and Viking images.
++ .PP
++ OCT89 Converted Voyager decompression program to handle Viking
++ compressed images.  Changed obuf to 'unsigned' to simplify computation
++ of checksum.
++ .PP
++ AUG89 Added code to get command line arguments for filenames and
++ output format; routines to free memory used by the Huffman tree);
++ fixed the SFDU label output length; and modified the I/O routines so
++ that the open for Host type 2 uses binary I/O.
++ .PP
++ JUN89 Fixed READVAR, to get length on 16-bit unswapped hosts.
++ .PP
++ JUL88 C driver to decompress standard Voyager Compressed images by
++ Mike Martin 1989/12/02.

++ 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.
++ 
++ At the moment, you can get this decidedly 'fine' piece of software via 
++ anonymous ftp on the following sites:
++ 
++    Hostname			Directory
++    --------			---------
++    ftp.cis.upenn.edu:		pub/xv
++    ftp.upenn.edu:		data/bradley
++    ftp.duke.edu:		pub/archive/xv
++    gatekeeper.dec.com:		pub/graphics/xv
++ 
++ The file is called 'xv-3.10.tar.gz' (or 'xv-3.10.tar.Z' if you don't have 
++ the 'gunzip' program).
++ 
++ BTW, if any of you fine folks can get these files put up on one of the major
++ ftp sites (wustl, gatekeeper, etc.) please do so, and let me know!
++ 
++ Enjoy!
++ 
++ John Bradley
++ 
++ -------------------------
++ Note:  These tar files (xv-3.10.tar.Z and xv-3.10.tar.gz) have been replaced
++   as of 12/22/94, as the initial ones wouldn't build correctly on VMS.
