+Various examples of GNU ptx usages.
+Francois Pinard <pinard@iro.umontreal.ca>, 1993.
+
+This directory contains a few examples contributed by GNU ptx users.
+Feel free to look at them for tricks or ideas.  When an example
+requires many files, a subdirectory is used to hold them together.
+I have not necessarily tested these examples recently, if at all.
+
+If you have examples you would like to share, please submit them to
+me.  You may also submit corrections to the examples given in this
+directory, however, please write to the authors first, since they most
+probably will like to have their say about their own contribution.
+
+* include.pl: A Perl script studying system include files.
+
+* luke/: A shell script permuting indices for man pages.  It contains
+two examples of an .xx definition for *roff, one simple, one complex.
+
+* latex/: A simple example of \xx definition for latex.
+
+* ajay/: A more complex application of latex with ptx.

+Subject: Re: Gptx suggestions and help request 
+Date: Tue, 28 Sep 93 11:30:04 +0500
+From: ajayshah@cmie.ernet.in
+
+[...] My plaintext input looks like: "pagenum multiword-phrase" where
+the multiword phrase is atmost five words.  So [...], I'm doing two
+columns in small type.
+
+I got one of the programmers here to write me a tex macro for my
+problem.  When it goes into production I'll mail you a few files: a
+sample input, the gptx command, the output, and the tex macro.  If you
+find these interesting you can ship them with future gptx releases.
+
+Thanks a lot for gptx.  If you have a mailing list of loyal users,
+you can add us to it :-)

+Date: Tue, 05 Oct 93 15:23:44 +0500
+From: ajayshah@zigma.cmie.ernet.in
+
+That is a full set of a files for an example of "production use".  You
+are welcome to post them, or use them as a sample supplied with the
+gptx distribution, etc., with absolutely no restrictions on what
+anyone does with this.  In case you do so, please acknowledge the
+contribution of Rakesh Chauhan, rk@cmie.ernet.in, who is the author of
+x.pl and header.tex.  [...]
+
+As you can tell, I used it for a 100% realworld problem, and it
+worked.  Thanks a million.  If you'd like, I can send you a hardcopy
+of the full finished document (just send me your mailing address).  If
+you would like to mention the name of this document when you use
+these files as a demo, it is

+From beebe@math.utah.edu Wed Oct 27 19:37:22 1993
+Date: Tue, 26 Oct 93 15:43:19 MDT
+From: "Nelson H. F. Beebe" <beebe@math.utah.edu>
+To: pinard@iro.umontreal.ca
+Subject: Re: Another short comment on gptx 0.2
+
+/usr/lib/eign:		DECstation 5000, ULTRIX 4.3
+			HP 9000/735, HP-UX 9.0
+			IBM RS/6000, AIX 2.3
+			IBM 3090, AIX MP370 2.1
+			Stardent 1520, OS 2.2
+			Sun SPARCstation, SunOS 4.x
+
+No eign anywhere on:	HP 375, BSD 4.3 (ptx.c is in /usr/src/usr.bin,
+				and the source code refers to /usr/lib/eign,
+				but I could not find it in the source tree)
+			NeXT, Mach 3.0 (though documented in man pages)
+			Sun SPARCstation, Solaris 2.x
+			SGI Indigo, IRIX 4.0.x
+			
+The contents of the eign files that I found on the above machines were
+almost identical.  With the exception of the Stardent and the IBM
+3090, there were only two such files, one with 150 words, and the
+other with 133, with only a few differences between them (some words
+in the 133-word file were not in the 150-word file).  I found the
+133-word variant in groff-1.06/src/indxbib.  I used archie to search
+for eign, and it found 7 sites, all with the groff versions.
+
+The Stardent and IBM 3090 eign files have the same contents as the
+150-word version, but have a multiline copyright comment at the
+beginning.  None of the others contains a copyright.
+
+I recently had occasion to build a similar list of words for bibindex,
+which indexes a BibTeX .bib file, and for which omission of common
+words, like articles and prepositions, helps to reduce the size of the
+index.  I didn't use eign to build that list, but instead, went
+through the word lists from 3.8MB of .bib files in the tuglib
+collection on ftp.math.utah.edu:pub/tex/bib, and collected words to be
+ignored.  That list includes words from several languages.  I'll leave
+it up to you to decide whether you wish to merge them or not; I
+suspect it may be a better design choice to keep a separate eign file
+for each language, although in my own application of ptx-ing
+bibliographies, the titles do occur in multiple languages, so a
+mixed-language eign is appropriate.  Since there are standard ISO
+2-letter abbreviations for every country, perhaps one could have
+eign.xy for country xy (of course, only approximately is country ==
+language).  The exact list of words in eign is not so critical; its
+only purpose is to reduce the size of the output by not indexing words
+that occur very frequently and have little content in themselves.
+
+I'm enclosing a shar bundle at the end of this message with the merger
+of the multiple eign versions (duplicates eliminated, and the list
+sorted into 179 unique words), followed by the bibindex list.
