-# 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
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures potrace (TeX Live) 1.15 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.

-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  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>
-  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.

-ChangeLog
-
-v1.15 2017/08/05
-	(2017/08/05) PS1 - use round() instead of rint()
-	(2017/08/05) PS1 - portability: set both _POSIX_C_SOURCE and
-	_NETBSD_SOURCE to enable strdup prototype in string.h, as
-	_XOPEN_SOURCE=500 doesn't work on macOS, _XOPEN_SOURCE=600 doesn't
-	work on SunOS, and _POSIX_C_SOURCE alone doesn't work on Minix.
-	(2017/08/02) PS1 - fixed a potential arithmetic overflow.
-	(2017/06/17) PS1 - fixed a bug with very large bitmaps. Reported
-	by Michael Voříšek.
-	(2017/03/05) PS1 - autoconf: added --enable-local-getopt to avoid
-	using the system-wide getopt library (it may still end up being
-	used on GNU systems).
-	(2017/03/05) PS1 - portability: moved getopt.h to a subdirectory,
-	to be included only when needed. Reported by Daniel Macks.
-	(2017/03/05) PS1 - portability: use _XOPEN_SOURCE=600 to fix macOS
-	warning.
-	(2017/02/27) PS1 - fixed more buffer overflows (not security
-	critical), including one reported by Agostino Sarubbo. This also
-	fixes CVE-2017-12067.
-
-v1.14 2017/02/19
-	(2017/02/19) PS1 - speed: use clang as default compiler if
-	available, and no longer use -ffloat-store even with gcc.
-	(2017/02/18) PS1 - corrected some exit codes, added some missing
-	error handlers.
-	(2017/02/17) PS1 - mkbitmap: bugfixes and improvements in parsing
-	image files.
-	(2017/02/15) PS1 - truncate the image size when bitmap data ends
-	prematurely. This fixes CVE-2016-8686, where Potrace appeared to
-	be "hanging" on a crafted input file.
-	(2017/02/14) PS1 - test suite: added tests for plain pnm files.
-	(2017/01/08) PS1 - fixed potential compiler issues due to signed
-	arithmetic overflow and arithmetic shifting.
-	(2017/01/07) PS1 - enable use of negative dy in bitmap data.
-	(2017/01/07) PS1 - test suite: moved data files to a subdirectory.
-	(2017/01/07) PS1 - test suite: added a check for -i flag.
-	(2017/01/07) PS1 - fixed buffer overflow CVE-2016-8685, reported
-	by Agostino Sarubbo.
-	(2015/10/24) PS1 - portability: use const char * for string
-	constants, required by C++11. Reported by Martin Gieseking.
-	(2015/10/24) PS1 - portability: extra spaces around string macros,
-	required by C++11. Reported by Martin Gieseking.
-	(2015/10/24) PS1 - portability: added more potential C compilers
-	to autoconf. Suggested by Nelson Beebe.
-
-v1.13 2015/10/22
-	(2015/07/18) PS1 - fixed heap overflows, null pointer dereference
-	bugs and a memory leak. Reported by Agostino Sarubbo.
-	(2015/05/17) PS1 - man page: show which backends are dimension
-	based, and state more clearly that svg backend defaults to 72dpi.
-	(2015/04/11) PS1 - portability: ssize_t not supported on some
-	systems; use ptrdiff_t instead. Reported by Martin Gieseking.
-	(2015/03/28) PS1 - portability: added missing #includes for c99,
-	reported by Nelson Beebe.
-	(2015/03/27) PS1 - include config.h before other header files,
-	reported by Peter Breitenlohner.
-	(2015/03/26) PS1 - fixed division by zero bug triggered by bitmap
-	of dimension 1x0. Reported by Tomasz Buchert.
-
-v1.12 2015/03/24
-	(2015/03/20) PS1 - fixed memory overflow bug triggered by very
-	large bitmaps. Fixes RedHat bug #955808 reported by Vincent Danen
-	and Debian bug #778646 reported by Moritz Muehlenhoff.
-	(2014/09/06) PS1 - test suite: added binary-check, to check that
-	files are written in binary mode. Mostly relevant on Windows.
-	(2014/09/06) PS1 - portability: fixed potential binary file mode
-	bug on MinGW64.
-	(2014/03/30) PS1 - man pages: fixed leading blank page with
-	groff -man -Tps.
-	(2013/12/29) PS1 - portability: made regular expressions in test
-	suite POSIX compliant, reported by Ben Bullock.
-	(2013/05/14) PS1 - distribution: removed libtool from distribution.
-
-v1.11 2013/02/19
-	(2013/02/10) PS1 - bitops.c: added "cc" as a clobbered register.
-	(2012/09/13) PS1 - GeoJSON backend: -u option affects rounding,
-	not scaling.
-	(2012/09/12) CH1 - added GeoJSON backend.
-	(2012/03/04) PS1 - minor change in behavior of alphamax parameter:
-	make a corner if alpha >= alphamax (instead of >). This makes
-	little practical difference, except when alphamax = 0, in which
-	case we now get a polygon. Fixes bug #3495854, reported by
-	scribbleink.
-	(2012/02/24) PS1 - added support for BMP format with bitfields.

-	(2003/08/07) PS1 - keep output flushed in postscript mode
-	(2003/08/07) PS1 - fixed memory leak in multiple page mode

- data. Portability has been improved to encompass C++11. The default
- compiler is now clang if available. Thanks to Nelson Beebe and Martin
- Gieseking for reporting portability issues, and to Agostino Sarubbo
- for reporting bugs.
-
-October 22, 2015: Release 1.13
-
- Some critical bugs in the processing of BMP files were fixed. These
- bugs allowed the program to be crashed, or potentially to be abused
- in other ways, by feeding it specially crafted BMP files. Thanks to
- Tomasz Buchert and Agostino Sarubbo for reporting these bugs.
- Portability was improved for C99 and for MSVC++. Thanks to Peter
- Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting
- portability issues.
-
-March 24, 2015: Release 1.12
-
- Fixed memory overflow bug triggered by very large bitmaps. Fixed
- binary file mode on 64-bit Windows. Portability improvements.
-
-February 19, 2013: Release 1.11
-
- A GeoJSON backend was added; thanks to Christoph Hormann for
- contributing this. Support for bitfields in the BMP format was
- added. A minor change was made to the behavior of the alphamax
- parameter; a value of 0 now gives a true polygon.
-
-August 19, 2011: Release 1.10
-
- A DXF backend was added. The output is in the drawing interchange
- format used by computer aided design software. Thanks to Jonas
- Benedett Dorr for testing. The Gimppath backend was changed to be
- compatible with current versions of Gimp. The EPS, PDF, and SVG
- backends now use high-resolution bounding boxes. The default scaling
- of the EPS, PDF, and SVG backends is now fixed at 72dpi. A new option
- --flat was added to the SVG backend. A new option --tight was added
- to remove whitespace around the input image before calculating its
- scaling and placement.
-
-December 21, 2010: Release 1.9
-
- The xfig and eps backends were improved, and a fixed pagesize PDF
- backend was added. Support for BMP version 4 and version 5 files, as
- well as top-down BMP files, was added. Minor speed improvements to
- Potrace and major speed improvements to mkbitmap. A Gaussian blur
- option was added to mkbitmap. Libtool is now used to build and
- optionally install the Potrace library. An optional simplified
- progress bar was added for dumb terminals. This release also contains
- some portability improvements, cross-compilation improvements, and
- minor bug fixes.
-
-April 9, 2007: Release 1.8
-
- This release contains minor bugfixes and portability improvements.
- Rotation is now implemented in the PDF backend.
-
-March 6, 2005: Release 1.7
- 
- This is a bugfix release. A bug in the progress bar code, which
- caused arithmetic exceptions on some 64-bit architectures, has been
- fixed.
-
-February 27, 2005: Release 1.6
-
- This release contains an algorithm improvement that leads to a
- speedup of 20-60% over previous versions of Potrace. A new PDF
- backend was added, courtesy of Tor Andersson. An option --progress
- was added for displaying a progress bar. The Windows version of
- Potrace now uses MinGW instead of Cygwin, eliminating the need to
- install a special DLL alongside the executable programs, and solving
- some problems with wildcards and executable PostScript files. Some
- spurious "premature end of file" messages were eliminated. The
- core functionality of Potrace was separated into a library with a
- documented API, making it easier for developers to incorporate
- Potrace into other GPL-licensed software.
-
-July 8, 2004: Release 1.5
-
- The LZW patent has finally expired in Canada. Therefore, postscript
- level 2 compression can now be implemented directly within Potrace,
- without having to rely on the external "compress" program. This
- release makes the necessary corrections.
-
-March 6, 2004: Release 1.4
-
- This is a bugfix release. Fixed the bug which sometimes caused
- Potrace to "hang" on large input files. Also fixed some bugs in the
- compression code. The presence of the "compress" program is now
- determined at run-time, rather than compile-time. No new features or
- command line options were added.
-
-January 15, 2004: Release 1.3
-
- This is primarily a bugfix release. Version 1.2 fatally crashed when
- applied to an empty (all white) bitmap. The options -2 and -3 are now
- ignored when unsupported, rather than causing an error.  There were
- some improvements to the test suite, autoconfiguration, and
- portability. The bounding box in the xfig backend was fixed, and the
- postscript output now has better page encapsulation. Bitmaps of
- dimension 0 are now tolerated better.
-
-December 23, 2003: Release 1.2
-
- New experimental Gimppath and XFig backends were added.  A separate
- program mkbitmap was added, which can be used as a preprocessor to
- Potrace. It turns greyscale or color images into high-quality
- bitmaps with optional scaling and filtering. New options --opaque,
- --group, and --fillcolor were added for greater flexibility in
- generating editable PostScript and SVG output. The bitmap
- decomposition algorithm was improved and can now take advantage of
- 64-bit platforms.  Portability and autoconfiguration were vastly
- improved, and a test suite was added. Runlength encoded BMP files can
- now be read. Some bugs in command line options were fixed.
-
-August 18, 2003: Release 1.1
-
- The most important new feature of this release is an SVG (scalable
- vector graphics) backend. This file format can be read by vector
- graphics manipulation programs such as sodipodi, as well as web
- browsers with an SVG plugin. I also added PGM, PPM, and BMP as
- additional input file formats. The new --blacklevel and --invert
- options control how non-black-and-white images are converted to
- bitmaps before being processed by Potrace. The implementation of a
- critical function has been improved to make Potrace even faster on
- large input files; this results in speedups of up to factor 3.3
- relative to Potrace 1.0. Autoconfiguration was improved, and the code
- was polished to compile on more different architectures. The error
- messages for wrong file formats were also improved.
-
-August 10, 2003: Release 1.0
-
- First public release.

-	   POTRACE - transform bitmaps into vector graphics
-			
-				* * *
-	   
-DESCRIPTION
-
- Potrace is a tool for tracing a bitmap, which means, transforming a
- bitmap into a smooth, scalable image.  The input is a bitmap (PBM,
- PGM, PPM, or BMP), and the output is one of several vector file
- formats.  A typical use is to create SVG or PDF files from scanned
- data, such as company or university logos, handwritten notes, etc.
- The resulting image is not "jaggy" like a bitmap, but smooth. It can
- then be rendered at any resolution.
-
- Potrace can currently produce the following output formats: SVG, PDF,
- EPS, PostScript, DXF, GeoJSON, PGM (for easy antialiasing of
- pixel-based images), Gimppath, and XFig. Additional backends might be
- added in the future.
-
- A separate program, mkbitmap, is also provided. This program can act
- as a pre-processor for Potrace, applying scaling and various filters
- to an image before converting it to a bitmap. This is useful for
- potracing greyscale and color images.
-
-DEPENDENCIES
-
- Potrace relies on the zlib library for PostScript level 3
- compression. This library is pre-installed on most modern systems. 
- If not present, it can be obtained from http://www.gzip.org/zlib/.
-
-COMPILATION
-
- For generic compilation instructions, see the file INSTALL.  In
- addition, the following compile time options (options to ./configure)
- are supported. 
-
-  --with-libpotrace       install Potrace library and headers (default: no)
-  --disable-zlib          disable PostScript level 3 compression
-  --enable-metric         use metric units (centimeters) as default
-  --enable-a4             use a4 as the default papersize
-  --enable-dumb-tty       use simplified ASCII-only progress bar
-  --enable-local-getopt   avoid using the system-wide getopt library
-
- See also ./configure --help.
-
-INSTALLING
-
- If you are installing from sources, just do "make install" as root.
- If you are installing from a binary distribution, just copy the

-POTRACE LIBRARY (FOR DEVELOPERS)
-
- As of Potrace release 1.6, the Potrace core functionality has been
- separated into a library libpotrace.a. This makes it easy to integrate
- tracing functionality into other GPL programs. The API of the library
- is defined in the header file potracelib.h, and is documented in
- doc/potracelib.pdf. It is not by default installed, but can be
- installed with the --with-libpotrace configuration option.
-
-DOCUMENTATION
-
- Usage information is contained in the man page:
- http://potrace.sourceforge.net/potrace.html
-
- Many common questions are answered in the FAQ:
- http://potrace.sourceforge.net/faq.html
-
- Some examples are given on the following web pages:
- http://potrace.sourceforge.net/samples.html
- http://potrace.sourceforge.net/mkbitmap.html

-	   POTRACE - transform bitmaps into vector graphics
-
-			  README for Windows
-  _________________________________________________________________
-
-This file contains instructions specific to the pre-compiled Windows
-distribution of Potrace. Please see the general README file and the
-man page for general information on usage, how to compile Potrace,
-etc.
-
-
-INSTALLATION for Windows:
-=========================
-
-Download the file potrace-XXX.win32.zip (or potrace-XXX.win64.zip if
-you want the 64-bit version).  Unpack it with your favorite unzipping
-tool, such as unzip, 7-Zip, WinZip, or just right-clicking on the
-file.
-
-If you have "tar" and "gunzip" installed, you may also get the tar.gz
-file instead of the zip file.
-
-The distribution includes the executable programs potrace.exe and
-mkbitmap.exe. You need to move these files to a place where Windows
-looks for programs, for example C:\WINDOWS. Alternatively, you can
-amend your PATH environment variable, by adding something like the
-following line to C:\AUTOEXEC.BAT:
-
-        PATH=%PATH%;C:\DIRECTORY\WHERE\FILES\ARE
-
-
-RUNNING:
-========
-
-For non-Windows specific usage information, see the file README.
-
-Potrace on Windows runs in much the same way as under Linux and other
-Unix-like operating systems. You must run Potrace from the command
-line (also known as the MSDOS Prompt). File names can be given in Unix
-style or Windows style, thus the following will both work:
-
- potrace h:/data/file.txt
- potrace h:\data\file.txt
-
-Wildcards can also be used, as in:
-
- potrace h:\data\*.*
- potrace h:/data/*.*

-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns -1.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most

-   also special states init and stop. emit[b, code] is a function
-   which emits the code 'code' as a b-bit value into the output
-   bitstream. hibit(n) returns the least number of binary digits
-   required to represent n.
-
-   init ---> {[], newdict, 258}
-
-     where [] is the empty string, and newdict maps each of the 256
-     singleton strings to itself. (Note that there are two special
-     output symbols 256 and 257, so that the next available one is
-     258). Note: hibit(258)=9.
-
-   {[], d, n} (input c) ---> (emit[hibit(n), 256]) {c, d, n}
-
-   {s,d,n} (input c) ---> {s*c,d,n}
-
-     if s!=[], s*c is in the domain of d. Here s*c is the strings s
-     extended by the character c.
-
-   {s,d,n} (input c) ---> (emit[hibit(n), d(s)]) {c,d',n+1}
-
-     if s!=[], s*c is not in the domain of d, and hibit(n+2) <= 12.
-     Here d'=d+{s*c->n}.
-

-
-   {[],d,n} (input EOD) ---> (emit[hibit(n), 256]) (emit[hibit(n), 257]) stop
-
-   Notes: 
-
-   * Each reachable state {s,d,n} satisfies hibit(n+1) <= 12.
-   * Only codes of 12 or fewer bits are emitted.
-   * Each reachable state {s,d,n} satisfies s=[] or s is in the domain of d.
-   * The domain of d is always prefix closed (except for the empty prefix)
-   * The state machine is deterministic and non-blocking.

-/* we use the following method. Given a point (x,y) (with real-valued
-   coordinates) in the plane, let (xi,yi) be the integer part of the
-   coordinates, i.e., xi=floor(x), yi=floor(y). Define a path from
-   (x,y) to infinity as follows: path(x,y) =
-   (x,y)--(xi+1,y)--(xi+1,yi)--(+infty,yi).  Now as the point (x,y)
-   moves smoothly across the plane, the path path(x,y) sweeps
-   (non-smoothly) across a certain area. We proportionately blacken
-   the area as the path moves "downward", and we whiten the area as
-   the path moves "upward". This way, after the point has traversed a
-   closed curve, the interior of the curve has been darkened
-   (counterclockwise movement) or lightened (clockwise movement). (The
-   "grey shift" is actually proportional to the winding number). By
-   choosing the above path with mostly integer coordinates, we achieve
-   that only pixels close to (x,y) receive grey values and are subject
-   to round-off errors. The grey value of pixels far away from (x,y)
-   is always in "integer" (where 0=black, 1=white).  As a special
-   trick, we keep an accumulator rm->a1, which holds a double value to
-   be added to the grey value to be added to the current pixel
-   (xi,yi).  Only when changing "current" pixels, we convert this
-   double value to an integer. This way we avoid round-off errors at
-   the meeting points of line segments. Another speedup measure is
-   that we sometimes use the rm->incrow_buf array to postpone
-   incrementing or decrementing an entire row. If incrow_buf[y]=x+1!=0,
-   then all the pixels (x,y),(x+1,y),(x+2,y),... are scheduled to be
-   incremented/decremented (which one is the case will be clear from 
-   context). This keeps the greymap operations reasonably local. */
