+2010-05-03  Jim Diamond <jim.diamond@acadiau.ca>
+
+	* pdfclose.c: make it work with all of AR{5,7,8,9} and xpdf.
+	* pdfopen.c:  add ability to parse and send function-keys.
+		      Add code (commented out) in an attempt to
+		      support okular (see code comments).
+	* sendx.c:    add code (commented out) in an attempt to
+		      support okular (see code comments).
+	* configure.ac: add changes suggested by Peter Breitenlohner.
+
+
+2010-04-24  Jim Diamond <jim.diamond@acadiau.ca>
+
+	* utils.[ch]: put a function to create window titles there
+	* xpdfopen.h: put constants related to the titles of various
+	              PDF viewers there
+	* pdfclose.c: modify to use utils.c and xpdfopen.h
+	* pdfopen.c:  major modifications so it works with AR7, AR8, AR9
+	              xpdf and maybe AR5, and so that it might be
+		      relatively straightforward to add other PDF viewers.
+		      The default viewer is AR9, this can be overridden
+		      by an environment variable and a command-line
+		      argument.
+	* sendx.c:    Reset the error status in open_channel() so that an
+		      error return doesn't become permanent.
+		      Fixed mask param in XSendEvent().
+	 
+
+2010-04-21  Jim Diamond <jim.diamond@acadiau.ca>
+
+	* pdfopen.c: Fold in some changes submitted by
+		     Peter Breitenlohner <tex-live@tug.org>
+	* pdfopen.c: Fold in some changes submitted by
+		     Peter Breitenlohner <tex-live@tug.org>
+		     and reformat the code.
+
+
+2010-04-11  Jim Diamond <jim.diamond@acadiau.ca>
+
+	* pdfopen.c: Update (in a non-backward-compatible way) to
+		     work with AR 9.  Save old version in pdfopen-AR-7-and-8.c.
+
+
+2009-08-22  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	Avoid maximal compiler warnings.
+	* pdfopen.c: Use strdup'ed literal string (malloc+strcpy) to
+	initialize non-constant string.
+	* sendx.[ch]: Constify string args of all functions.
+	Consistently use wname for window name string param.
+	(close_channel): ANSI C function definition.
+
+
+2009-08-19  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	* Makefile.am (AM_CFLAGS), configure.ac: Enable compiler warnings.
+	* pdfopen.c (usage), pdfclose.c (usage): Declare as static.
+
+	* sendx.h (new): Declare prototypes for functions in sendx.c.
+	* Makefile.am (pdfopen_SOURCES, pdfclose_SOURCES): Add sendx.h.
+	* pdfopen.c, pdfclose.c, sendx.c: #include "sendx.h".
+
+	* sendx.c (GetRootWindow): Slightly reformulate to avoid compiler
+	warning (strict-aliasing rules).
+
+
+2009-05-06  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	Adapt to TL2009 build system.

+Pdfopen 0.80 - Send open/close commands to Acrobat Reader and xpdf
+------------------------------------------------------------------
+
+This is a Linux (X11) implementation of Fabrice Popineau's pdfclose/
+pdfopen commands to control Acrobat Reader and xpdf.
+
+The libX code was borrowed from Reinhard Fobbe's Sendx library for 
+Tcl/Tk, and the programs use the same license, copied below. 
+
+Version 0.3 adds support for Adobe Reader 7.0 for Linux.
+(different window titles and key shortcuts)
+
+Version 0.4 uses autoconf
+
+Version 0.5 fixes an incorrect autoconf variable, supports
+building under X11R5, handles pathnames on the command-line, 
+and  fixes a bug where pdfopen did not exit correctly after 
+(automatically) starting acroread.
+
+Version 0.51 uses the strrchr() function instead of rindex() 
+to allow compilation on non-BSD derived unix platforms.
+
+Version 0.61 attempts to do something useful with Adobe Reader 8,
+even though it is impossible to restore the viewport.
+
+Version 0.80 adds an implementation for AR 9 and xpdf.
+
+The AR command lines do not behave precisely the same as under Windows, 
+because the Linux Reader behaves somewhat differently: it is not 
+scriptable, but it is possible to 'fake' keypresses.
+
+
+pdfopen has the following call sequence:
+	pdfopen [-viewer <ar9|ar9-tab|ar8|ar7|ar5|xpdf>] <pdf file name>
+The 'ar9' version uses the '-openInNewWindow' option, the 'ar9-tab'
+version does not (so if there is already an AR9 window open, a new tab
+will be opened in that window).
+
+
+pdfclose has the following call sequence:
+	pdfclose <pdf file name>
+This program closes an existing AR5, AR7, AR8, AR9 or xpdf window
+displaying the given PDF file.
+
+
+Version 0.80 compiles on Linux (Slackware64 13.0, anyway) with
+the following command:
+	gcc -Wall pdfopen.c sendx.c utils.c -o pdfopen -lX11 -s
+should you not want to go through the process of creating and running
+a configure program.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures xpdfopen for TeX Live 0.80 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  XMKMF       Path to xmkmf, Makefile generator for X Window System
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ * Note 3: Unlike xpdf and AR[5,7,8,9], okular will not accept X events
+ * from this program unless the okular window has focus.  On my system
+ * (Slackware64 13.0, using fvwm2), the functions I added to sendx.c to try

+\chapter{Controlling Acrobat Reader under X11}
+
+
+\centerline{Taco Hoekwater, taco(at)aanhet.net}
+
+\blank[3*line]
+
+Most people who use the Acrobat Reader to preview PDF files
+generated from \TeX\ documents will know that it is a hassle to
+deal with documents that need to be compiled while being viewed.
+
+The Linux version of Adobe's program simply does not notice that the
+PDF file has changed, and the Microsoft Windows version is even worse:
+it opens the PDF file using mandatory locking, making it absolutely
+impossible to recompile the document while it is still open in the
+Reader.
+
+Common practice using Acrobat Reader for viewing PDF's generated from
+pdf\TeX{} is therefore to cycle through these actions, either from
+the command line or from a script:
+
+\startitemize[n]
+\item edit the \TeX{} source
+\item compile to PDF
+\item view with Acrobat Reader
+\item close Acrobat Reader
+\stopitemize
+It follows that the Reader has to make a complete restart for each
+cycle, which is a slow operation. The alternative would be to run the
+Reader in the background and ask users to, after steps 1.~and 2.,
+manually close and reopen the document. That is not user-friendly, of
+course, and that's where \type{pdfopen} and \type{pdfclose}, described
+in this article, will be useful.
+
+Because the problem was much more severe under Windows, a few years ago
+Fabrice Popineau has written two small programs that use DDE calls to
+control the Reader from an external script or batchfile:
+\startitemize
+\item \type{pdfclose} to make the Reader close the file before the
+compilation starts
+\item \type{pdfopen} to re-open the file afterwards.
+\stopitemize
+The Linux X11 versions are command||line compatible with Fabrice's
+originals, but they do not function completely identically.
+
+\starttyping
+pdfclose --file <pdf file>
+\stoptyping
+This will close an X window with the name \type{<pdf file>} (for
+Acrobat Reader~5) or the name \type{Adobe Reader - <pdf file>}
+(for Adobe Reader~7).
+
+\starttyping
+pdfclose --all
+\stoptyping
+The Linux \type{pdfclose} command ignores the \type{-}\type{-all}
+command||line switch. The Windows version will close {\it only\/} the
+files that were opened through \type{pdfopen} when \type{-}\type{-all} is
+given, and this cannot easily be done under X. Ignoring the options
+seems wiser than unconditionally closing all open PDF documents.
+
+\starttyping
+pdfopen
+\stoptyping
+This command||line sends a ``go to previous document'' to an already
+existing, but empty, Adobe Reader window.  There are perhaps some
+situations where this possibility might come in handy.
+
+
+\starttyping
+pdfopen --file <pdf file> [--page <pagenumber>]
+\stoptyping
+The Linux version silently ignores a given
+\type{-}\type{-page} option, because its behaviour would be near||impossible to
+predict. The program also reacts a bit differently to the
+\type{-}\type{-file} option: if the file is already open in the
+Reader, it will close and re||open the document. 
+
+Normally, this is the command you want to use under Linux, because it
+immediately re||opesn the PDF file you have given as an argument in
+the Reader, using the same page \& view settings. The result is {\it
+almost\/} as if there was a refresh command in the Reader. {\it
+Almost\/}, because it only works if just this document is open for
+viewing, not if there are more files opened.
+
+\blank
+I've tested my programs with Acrobat Reader 5.0.10 under Mandrake
+Linux 10.1 using X.org 6.8.2, but the code is reasonably generic and
+should work out of the box using most X11R6 implementations. 
+Version 0.5 compiles under X11R5 as well.
+
+Adobe Reader 7.0 is OK as long as you keep your PDF files maximized
+within the main Adobe Reader window (the PDF document's name has to
+appear in the window title). Also, you probably want to set the
+preference {\it Reopen documents to last viewed page\/} to ``All
+files''. You can find this setting in the {\it Startup\/} page of the
+preferences screen.
