Subject: alt.binaries.pictures FAQ - OS specific info
Last-modified: 13 November 1992

	This is part 3 of the FAQ for the alt.binaries.pictures* hierarchy.  
    This part of the alt.binaries.pictures FAQ contains information specific
    to particular systems and on available utilities.

      For information on issues of etiquette and posting policy and/or 
    suggestions, consult part 1 of this posting.

      For information on "general", or operating-system independent 
    information, questions you may have about the pictures newsgroups, 
    decoding and encoding techniques, or picture formats, consult part 2 
    of this posting.

    Before posting to these groups for the first time, please check the FAQ
    list (this posting - including parts 1 and 2), and also read the newsgroup 
    news.announce.newusers, which contains many answers to questions about 
    UseNet in general.

    If you've read previous versions of this FAQ, you'll probably only want
    to read anything that has changed since the last distribution.  These
    changes appear both in this document and in the accompanying "Changes to
    the alt.binaries.pictures FAQ".  Note that this is a "live" document, and 
    is always getting important information added or updated.

***********************************************************************
Before you miss an important detail contained in this file, let me
"pre-repeat" that *many* programs mentioned in this document are available 
for anonymous ftp at bongo.cc.utexas.edu (128.83.186.13), in the gifstuff 
directory.  Also: there are NO GIF files of any kind at this site!  Save
your time and don't bother looking for them!
Additionally, the file "ftpsites" on bongo in the gifstuff directory gives
many examples of places to find these utilities.

I. UTILITY SUBMISSION GUIDELINES
Ever since the new format was adopted, lots of people want to see their 
favorite utility listed here!  That's great - the whole idea behind this 
FAQ is sharing the net wisdom (most of whats in this FAQ represents the 
combined knowledge of the pictures and graphics community's readership).
BUT... in order to include information on a particular utility, it has to
meet the following criterion:
    1) It has to fit into one of the classifications that make sense for
       pictures (viewers, converters, decoders, posters/unposters, etc).
    2) It's either Public Domain, FreeWare, or ShareWare software.  It
       doesn't make a lot of sense for this FAQ to become one big 
       advertisement!
    3) It has to be readily available.  It doesn't do me (or anyone else,
       for that matter) much good to know "I don't know where I got it,
       but the MajorHonkinTool utility solves all my problems...".
So, to submit a utility, I need to know (in as much detail as you can
possibly give):
    A) What's the utility's name,
    B) What it does,
    C) What platforms it runs on (probably one or more of the ones listed
       in this FAQ are most appropriate =:^) ),
    D) Where to get it.  Anonymous FTP or mail server archive is the best, 
	 but if it's been posted to a newsgroup, that would be OK, too.  If
	 you want to set yourself up as an e-mail distribution for a utility,
	 that's OK too - but be prepared for a deluge of requests!  I WILL
	 NOT accept someone else's address as an e-mail distribution unless
	 they specifically send their approval (for obvious reasons).  Don't
	 just send me something expecting that I'll put it on bongo, either
	 - bongo has very limited file resources (and is pretty much at its 
	 quota already)!
Without the full information above, I can't list the utility in this FAQ in 
good conscience, since it won't be very useful...
Please keep up the good work and let me know how this document should be
kept up-to-date!


II. COMMON FTP SITES

There are a few sites out there that are mentioned time and time again in 
this document.  In order to save a little space (and make things easier to 
maintain), the following convention has been devised.  The shorthand for
a site or sites is listed first, the site address(es) is noted, and any
special information relative to the sites is also given.  Hope this isn't
too confusing!

BONGO			bongo.cc.utexas.edu (128.83.186.13)
        In this FAQ, a notation of "BONGO:some_file_path" means that you 
	can find the file on bongo in /gifstuff/<some_file_path>.
EXPORT			export.lcs.mit.edu (18.24.0.12)
        In this FAQ, a notation of "EXPORT:some_file_path" means that you 
	can find the file on export in /pub/contrib/<some_file_path>.
SIMTEL			wsmr-simtel20.army.mil (192.88.110.20)
	In this FAQ, a notation of "SIMTEL:some_file_path" means that you
	can find the file on simtel in pd1:<some_file_path>.
WUARCHIVE		wuarchive.wustl.edu (128.252.135.4)
        In this FAQ, a notation of "WUARCHIVE:some_file_path" means that you 
	can find the file on wuarchive in <some_file_path>.
OAKLAND			oak.oakland.edu (141.210.10.117)
	In this FAQ, a notation of "OAKLAND:some_file_path" means that you 
	can find the file on oakland in <some_file_path>.
MIRRORS			wsmr-simtel20.army.mil (192.88.110.20),
			wuarchive.wustl.edu (128.252.135.4),
	These hosts "mirror" a lot of common information.  In this FAQ, if you
	see the notation "MIRRORS:some/file/path", this means that you
	can find the file on simtel in pd1:some.file.path, and on its mirror
	site (wuarchive) in /mirrors/some/file/path.
GARBO			garbo.uwasa.fi (128.214.87.1)
	In this FAQ, a notation of "GARBO:some_file_path" means that you 
	can find the file on garbo in <some_file_path>.


III. PORTABLE UTILITIES

"GENERAL UTILITY" TOOLS:
GIFtest.c           	Tests integrity of GIF files.
	Available via anonymous FTP from BONGO:gifutils/giftest.c, or from
	ftp.rahul.net (192.160.13.1) in /pub/bryanw.

DECODERS/ENCODERS:
unc			"Smart decoder" by Mark Maimone (mwm@cs.cmu.edu) - uses
			article headers to determine the posting order and puts
			parts in appropriately named files to aid processing
			through uudecode.  Newest version handles missing or 
			"noisy" info in Subject: lines more gracefully, and also
			provides better MS-DOS support.  Portable only across
			UNIX and MS-DOS systems (so far).  Mark is interested
			in any port feedback you can give him - especially VMS.
			He's even willing to help with the porting effort!
	Available via anonymous FTP on vacation.venari.cs.cmu.edu 
	(128.2.209.207) in directory /usr/anon, file unc-*.Z (or exploded files
	in the unc-* directory - also posted to alt.sources).

COMPRESSION/DECOMPRESSION TOOLS:
cjpeg/djpeg 		Free, portable C code for JPEG compression from the 
			Independent JPEG Group, lead by Tom Lane 
			(tgl+@cs.cmu.edu).  This software has been tested on 
			numerous Unix machines, PCs, Macs, and Amigas; it is
			believed that it can be ported to almost any machine 
			that has a (reasonable) C compiler.
	Available via anonymous FTP from several places.  The "official" 
	archive site for this source code is ftp.uu.net (137.39.1.9 or 
	192.48.96.9).  Look under directory /graphics/jpeg; the file to 
	retrieve is jpegsrc.v?.tar.Z.  You can retrieve this file by FTP or 
	UUCP.  Folks in Europe may find it easier to FTP from nic.funet.fi 
	(see directory /pub/graphics/programs/jpeg).  The source code is also 
	available on CompuServe, in the GRAPHSUPPORT forum (GO PICS), library 
	10, as jpsrc*.zip.
	If you are not reasonably handy at configuring and installing portable 
	C programs, you may have some difficulty installing the free source 
	code.  There is currently an FTP archive of pre-built executable 
	versions of the free JPEG code for various machines, accessible at 
	ftp.cis.ksu.edu (129.130.10.80); look under /pub/JPEG to see what is 
	currently available.  The administrators ask that FTP traffic to this 
	system be limited to non-prime hours.

CONVERSION TOOLS:
PBMPlus tool kit 	Maintained by Jef Poskanzer (jef@well.sf.ca.us).  Very
			nearly a de-facto standard for converting between many
			different formats.  Includes "utility" tools to scale,
			quantize, crop, flip, rotate, and many other graphics
			operations.
	Available via anonymous FTP from EXPORT:pbmplus*.tar.Z and from 
  	ftp.ee.lbl.gov (128.3.112.20) as /pbmplus*.tar.Z.  Visit the newsgroup 
	alt.graphics.pixutils for more details, discussion of usage, etc.
UtahRaster Tools	Converts between many file formats, somewhat similar
			to the PBMPlus tool kit.
	Available via anonymous FTP from 
	WUARCHIVE:/graphics/graphics/packages/urt/urt-*.tar.Z
GIFtoPS			GIF to postscript converter.
	Available via anonymous FTP from BONGO:gifutils/giftops.c.


IV. MS-DOS PROCEDURES/UTILITIES

There is an archive of MS-DOS OS/2 tools available either via anonymous FTP 
(on hobbes.nmsu.edu - 128.123.35.151) or via e-mail, by sending a one-line 
mail command message.  Many of the utilities listed in this section can be 
obtained here;  these will be identified by the notation
"HOBBES:<archive-file>(<mail name>)".
This would mean that you could get that utility in the pathname specified as
/pub/os2/general/graphics/<archive-file>, or via e-mail by sending a message
containing "GET <mail name> OS2" to LISTSERV@BLEKUL11.BITNET.
I might also suggest to OS/2 users that you get a copy of the index (one-line 
e-mail message is "INDEX") and help (one-line e-mail message is "HELP") for 
this site - there's over 150M of OS/2 programs, and the list is growing...

VII. Atari UTILITIES

There is a wonderful archive of Atari tools available either via anonymous 
FTP (on atari.archive.umich.edu - 141.211.164.8) or via e-mail, by sending a 
one-line mail command message.  Many of the utilities listed in this section 
can be obtained here;  these will be identified by the notation
"ATARI-ARCHIVE: <archive-file>".
This would mean that you could get that utility in the pathname specified as
atari/<archive-file>, or via e-mail by sending a one-line e-mail message 
containing "send <archive-file>" to atari@atari.archive.umich.edu.
I might also suggest to fellow Atari-ites (Atarions?) that you get a copy
of the index (one-line e-mail message is "index") and help (one-line e-mail 
message is "help") for this site - there's all *sorts* of good stuff out 
there!

Consult the comp.sys.next* news groups for NeXT-specific information.


X. UNIX/XWINDOWS PROCEDURES/UTILITIES

There is an "unofficial" archive of a lot of UNIX utilities at uranie.inria.fr,
maintained by Nathan Maman (maman@uranie.inria.fr).  For purposes of this FAQ,
this site will be identified by the notation:
	URANIE:<filename>
...which means that <filename> is available on uranie.inria.fr in directory
/pub/images/scripts.  There are utilities on this site that are not mentioned
in this FAQ, but are definitely worth checking out...
Also, the best place to look for any sort of X utility is on EXPORT.  There
are all sorts of X applications archived there, and should probably be your
first resort as to where to find any given X utility.

SYSTEM-SPECIFIC PROCEDURES:
    * To concatenate multi-part picture files together and decode, execute:
  cat part1 part2 part3 ... partN | uudecode
    * To encode a file for posting, (assuming the file is named fyle - encoded
      output will be in fyle.uu):
  uuencode fyle fyle > fyle.uu
    * To split a uuencoded file into multiple parts, use the "split" utility
      (assuming the file containing the uuencoded data is fyle.uu - split 
      output will be in files fyle_<two-char-code>, where <two-char-code> is 
      "aa", "ab", "ac", etc.):
  split -1000 fyle.uu fyle_
    * Of course, it's possible to combine the encoding and splitting steps
      into one operation using pipes (same example as above):
  uuencode fyle fyle | split -1000 - fyle_
    * Sometimes, files get posted with Mac "header" information in it.  To get
      rid of this extraneous information (assuming the Mac file is named 
      "macfile", the output file will be named "newfile"):
  dd if=macfile of=newfile bs=128 skip=1

DECODERS/ENCODERS:
aub			"Smart automatic decoder" by Mark Stantz (written in 
			perl). aub connects to an NNTP-based news server or to
			raw spooled news files and scans for new pieces of 
			split, encoded binaries that have recently been 
			received.  Binaries are expected to contain subject 
			lines conformant with de-facto UseNet standards; aub 
			may not be able to identify pieces of binaries which are
			not named according to accepted  conventional practice.  			If new binaries are found, aub retrieves, organizes and
			decodes them, leaving the decoded files in a 
			configurable location.  aub also allows for conditional
			decoding and postprocessing of decoded binaries.  Highly
			recommended by me (deej) as a time-saver - I run it from
			cron nightly!
	Available via anonymous FTP on liasun3.epfl.ch (128.178.36.30) as 
	/pub/util/aub-1.0, or at ftp.cc.gatech.edu (130.207.119.241) as 
	/pub/unix/aub.tar.Z, at URANIE:aub-1.0.shar.Z, the "official" archive
	at sgigate.sgi.com (192.82.208.1) in pub/aub/aub.2.0.5.shar, or from
	ftp.rahul.net (192.160.13.1) in /pub/bryanw/unix.  Also posted to
	alt.sources.

			William J Middleton (middle@cse.uta.edu).
	Available via anonymous FTP from URANIE:dlhunter.*.
mcvert			Decodes Macintosh BinHex files.
	Available via anonymous FTP from sumex-aim.stanford.edu (36.44.0.6) in 
	directory /info-mac/unix, or from 
	WUARCHIVE:/mirrors/info-mac/unix/mcvert-*.tar.Z.

			(maman@uranie.inria.fr).
	Available via anonymous FTP from URANIE:myuud.c.
sift2			Automatic graphic file extractor/decoder by Tom Yager.
	Available via anonymous FTP from URANIE:sift2.*.
sortuud			Combines multi-part images - by Nathan Maman
			(maman@uranie.inria.fr).
	Available via anonymous FTP from URANIE:sortuud (URANIE:douud will use
	sortuud in a more automated manner).
splituue		Splits images and post them - by Nathan Maman
			(maman@uranie.inria.fr).
	Available via anonymous FTP from URANIE:splituue.
undo			Undo an archive from the net - by Tim Steele.
	Available via anonymous FTP from URANIE:undo-*.

	Available via anonymous FTP from ftp.rahul.net (192.160.13.1) in 
	/pub/bryanw/unix.
uudecode/uuencode	(normally UNIX standard)
	Available via anonymous FTP from BONGO:uutools/uudecode.c,uuencode.txt.
uuxfer			"Smart decoder/encoder" written by Dave Read.
	Available via anonymous FTP from BONGO:uutools/uuxfer*.
uucat			"Smart decoder", will concatenate the files you 
			specify, removing the headers and trailers almost 
			flawlessly.  Usage: 
			uucat file1 .. fileN | uudecode
	Available via anonymous FTP from BONGO:uutools/uucat.c.
uuconvert		"Smart decoder" written by Jeff Wiegley 
			(wiegley@girtab.usc.edu).  Incorporates uudecode 
			into uucat so that running uuconvert gets the job 
			done in one fell swoop.  Also allows you to store 
			all the parts to a picture or multiple pictures in 
			ONE file (in order) and run uuconvert on that one file.
			EMPHATICALLY recommended by Steve Quinn, who adds a 
			tip for interested people, "If you use UUCONVERT, 
			here's a really good downloading strategy I've evolved 
			with rn:  
			1) Run the list of subjects with '='.  
			2) Choose a picture and type 'id#1,id#2,...id#N:s 
			   filename' to save all the parts in one file (where 
			   id is the article number, and #N in the part of the 
			   picture).  You can also use id#1-id#N if they're 
			   posted in order.  
			3) Do this with many files (in separate file names).  
			4) When I get out of rn I do a convert *.gf' (where gf 
			   is just the extension I use when saving UUENCODED
			   GIF files), and all my files are decoded and ready 
			   to go.   (Well, most of the time it gets them all 
			   on a wildcard, but it's been known to miss others 
			   sometimes.  Double check before you destroy your 
			   UUENCODED copies.)
			If I find a whole string of pix I want, and all the 
			parts are in order, I do a id#1-id#N through the whole 
			set of them and save them all to one file."
	Available via anonymous FTP from BONGO:uutools/uuconvert.c.
viewer 			Allows you to view or archive pictures directly from 
			NNTP with no user intervention whatsoever.  It even 
			scans the article headers to determine which pieces go 
			together, and in what order.  It will optionally open 
			an X window to display the pictures.  So once you've 
			installed it, you just type "viewer", and sit back.
	Available via anonymous ftp from cs.utk.edu in ~ftp/pub/viewer*.
xmitBin			Binary file poster/mailer (includes picture stats and
			anonymous posting capabilities) by Jim Howard 
			(deej@cadence.com).  Latest version is 1.8.
	Available via anonymous FTP from URANIE:xmitBin.tar.Z, or from
	ftp.rahul.net (192.160.13.1) in /pub/bryanw/unix.

Several people have also written scripts in AWK, SED, or PERL which will 
strip headers and trailers, concatenate the results and pipe them through 
UUDECODE.  See section XI. (Appendix) if you want to run one of these.

COMPRESSION/DECOMPRESSION TOOLS:
compress/uncompress	(normally UNIX standard)
unzip			Uncompresses MS-DOS ZIP files.
	Available via anonymous FTP from SIMTEL:<unix-c.file-mgmt>unzip*.tar-z,
	and from WUARCHIVE:/mirrors/misc/unix/unzip*.tar-z, or from 
	GARBO:/unix/arcers directory as unzip*.tar.Z (you'll have to decompress
	these with the UNIX compress utility).  Also supposedly available from 
	WUARCHIVE:/mirrors2/ka9q/util/unzip.tar.Z.
lha			Uncompresses LZH (LHarc) files.
	Available via anonymous FTP from akiu.gw.tohoku.ac.jp in directory
	/pub/unix/lha as file lha-*.tar.Z, from lysator.liu.se in the
	/pub/amiga/LhA directory, and from sun.soe.clarkson.edu in /pub/src.

CONVERSION TOOLS:
dltogl			Converts DL files to GL files - written by 
			phillips@cs.ubc.ca.  (Usage note from Neil Nelson -
			nkn@solbourne.com):  There have been a few comments of 
			late concerning the use of dltogl and xgrasp.  It *is* 
			possible to make the two coexist.  dltogl can be used 
			one of two ways:
				1) dltogl file.dl file.gl
				2) dltogl file.dl
			The first method produces a gl file which will cause 
			xgrasp to drop a core (although xviewgl has no trouble 
			showing the resulting gl file).  The second method 
			will decode file.dl, leaving the constituent parts in 
			the current directory.  One of the files will be called 			dl.txt.  Simply rename this to file.txt, and then run 
			glib -u file.gl file.txt <all of the .clp and .pic 
			files produced by dltogl> to build the corresponding 
			gl file.  I don't know why renaming the .txt file 
			makes xgrasp happy, but it does.  See the shell script
			"dltogl2" in the Appendix to automate this process.
	Available via anonymous FTP on reseq.regent.e-technik.tu-muenchen.de

XI. APPENDICES: AWK, SED, AND PERL SCRIPTS

Below are the scripts mentioned in the previous section.  I make no 
assurances as to how well they work;  I use one of the 'super' uudecodes 
instead.  Note that the SED script will not work unless people follow this 
recent trend of putting 'BEGIN' and 'END' in the 'cut here' lines.  The 
AWK and PERL scripts will work on most files, but some uuencodes put out 
non-standard data, in which case these scripts will bomb and you'll have 
to do the work by hand.
-------------------------------------------------------------------------
AWK script:

#!/bin/sh

if [ X$1 != X ] ; then cat $* ; else cat <& 0 ; fi		| \
awk '/begin [0-9]/				{ok = 1}
     /^Message/					{ok = 0;next}
     /^M/ && (length == 61 || length == 62)	{ok = 1}
     /[cC]ut [hH]ere/				{ok = 0;next}
     /^END-----/				{ok = 0;next}
     /^Path:/					{ok = 0;next}
     /^$/					{ok = 0;next}
     /^-/					{ok = 0;next}
     /^_/					{ok = 0;next}
     {if (ok) print}
     /^end/					{ok = 0}' $* 	| \
(cd $HOME/tmp; uudecode)

--------------------------------------------------------------------------

SED idea from Alan Sparks (asparks@viewlogic.com):

cat $* | sed '/^END/, /^BEGIN/d' | uudecode


Recall that this won't work except on files with BEGIN and END as part 
of the 'CUT HERE' lines...

-------------------------------------------------------------------------

PERL script from Dave Mack (csu@alembic.acs.com):

#! /usr/local/bin/perl
#
# Combine split uuencoded files into a single data stream with
# e-mail garbage removed and pipe into uudecode. The uuencoded
# files must be in the correct order on the command line - in
# particular the first file must contain the "begin" line and
# the last file must contain the "end" line.
#
# WARNING: this code relies on uuencode putting out all lines
# of the form "M[61 ASCII characters]\n" for every line of the
# file except the last few before the "end" line. If you come
# across a uuencoded file that doesn't do this, you'll need to
# modify the code to handle it.
#
# DISCLAIMER: You use this code at your own risk. Also, don't
# take this is as a sterling example of Perl programming. Corrections
# and improvements welcome. You may do whatever you like with this
# code as long as you leave in some reminder of who the original
# culprit^H^H^H^H^H^H^Hauthor was.
#
# Usage: uumerge filename [filename...]
# Requires Perl 3.0 - my copy is at patchlevel 18

# Dave Mack csu@alembic.ACS.COM
#
# TODO: modify to allow more than one collection of files on
#	command line.
#
# KNOWN BUGS: 
#
# If some bozo puts a line beginning with "M" in the body of one
# of the intermediate/last chunks, uumerge will assume that uuencoded
# part starts there.
#
# If the last chunk only contains the last two or three lines of
# the uuencoded file (the ones that don't start with "M"), uumerge
# will die.
#
# CHANGES
#
# PATCH 1:
# It appears that some versions of uudecode are too stupid to skip
# past the lines preceding the "begin" line, so feeding a one-part
# uuencoded file to uumerge will bomb.

Yet another awk script - this one from Nasir Ahmed Noor

#! /bin/sh
# A shell script to extract binary files from their uudecoded parts.
# WRITTEN BY NASIR AHMED NOOR (noor@muug.mb.ca)
#
# Usage:
# Store all uudecoded parts of a file (in right order) in a file and give 
# that file as argument to this script. AN INPUT FILE CAN CONTAIN UUDECODED
# PARTS OF MORE THAN ONE FILE AND THEY ALL WILL BE EXTRACTED. You can
# provide multiple file names [wild cards also ok] on the command line.
