Thanks go to:

Jeroen Vreeken
		*** Original writer of this great program! ***
		From 3.1.12 these contributions:
		- Rewrite of PWC tracking code.
		- Motion-control action.quit fix.
		- Added tracking options to xmlrpc interface.
		- Ignore SIGPIPE (crashes webcam code).
		- Changed fast algorithm to imgs.size/10000 steps.
		- Renamed prerecord to pre_capture to be more consistent with
		post_capture.
		- Redone pre_capture completly.
		
Kalle Andersson
		- Created a patch that ensures that Motion detaches from
		the stdin and stout devices so that a secure shell that was used to
		start Motion in daemon mode does not hang when you exit the shell.
		
Ryan Ayers
		- Implemented improvement of vid_putpipe so that Motion does not
		spend time writing to a vloopback device which is not there.
		Also introduced reporting to syslog of writing to vloopback
		fails.
		- Improved configure's ability to find custom installations of
		ffmpeg.
		- Misc. cosmetic changes in the code.
		- Rewrote the ffmpeg functions completely added support for
		new codecs/formats mpeg4 and msmpeg4. mpeg1 was improved also.
		- Misc. improvement of the mpeg4 feature and new ffmpeg code.

Paul Beltrani
		- Implemented a fix/work around to a bug related to building and installing
		RPMs on Suse.

Michael Newlyn Blake
		- For setting up the motion mailinglist and the onsave command.

Mathias Bogaert
		- Lots of good ideas and the motion logos

William M Brack
		- Added patch that enables Motion to work with vloopback version 0.94
		and kernel 2.6.10+.
		http://www.lavrsen.dk/twiki/bin/view/Motion/MotionAndVloopbackVideoDotCPatch
		- Added support in configure for athlon64 from
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x190907
		(Angel Carpintero and William M Brack) 
		- Fixed some gcc warnings 
		- Code cleanup from a valgrind analysis.
		- Implemented WebcamShortWriteHandling patch
		http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch
		- Small code cleanup in motion.c for the variable holding the number of
		microseconds since epoch. The old code worked fine but relied on an integer
		overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen)
		- Complete rewrite of the Netcam code. Should fix many of the reported and
		still open netcam bugs. 
		http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamCodeRewritePatch
		- Improved the error reporting in the Netcam code and did a few minor
		corrections and code cleansups.
		- Implemented a much easier to use motion_log function which replaces the
		calls to prinf and syslog. The implementation to actually use this has been
		implemented in video.c and the Netcam code files. Rest will be in next snap.
		This code change as no impact to the user.
		http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
		- Fixed a buf in video.c so that VIDEO_PALETTE_GREY cameras now actually work.
		- Re-mplementation of optional Proxy Server for Network Cameras.
		http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamProxyServerPatch
		- Added the missing rotate feature in the new netcam code (Billl Brack)
		- Netcam error handling improvements and cleanup from Walgrind analysis.
		- Added a configure option --with-developer-flags which enables many compiler
		warnings that can be used by developers to make code more robust. Not
		for normal users building Motion.

Ashley Cambrell
		- PostgreSQL support, put_jpeg_grey(), webcam bugfixes.

Angel Carpintero
		- Improved configure process which automatically detects presence
		of xmlrpc-c and ffmpeg and makes the Makefile accordingly.
		- Improvement of configure reporting of missing shared libraries.
		- Fix for building motion without ffmpeg (missing #ifdef round newly
		added ffmpeg timelapse code)

		CPU specific compiler optimizations introduced with the rotate phase 2
		patch.
		- Implemented Streaming Netcam Without Curl which enables connecting to
		network cameras both with single jpeg frame mode and streaming mjpeg
		mode. This enables much higher framerates with Netcams. (with
		Christopher Price).
		- Improved the Netcam patch (Angel Carpintero)
		http://www.lavrsen.dk/twiki/pub/Motion/StreamingNetcamWithoutCurl/
		(pre2 patch fixes problem with not detecting Content-length and segfaults

		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x180550
		- Fixed compatibility problem with Palantir. Fixed by making output more
		compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel
		Carpintero. However this fix made Firefox flicker even more than it normally
		does. Final fix which works in both Palantir client, Firefox and Cambozola

		- http lockup bugfixes and ConvertSignalToSigaction only for webhttpd
		- alg_draw_location: Use temporary variables to store the values used in
		for() loops instead of compute them in each loop
		http://www.lavrsen.dk/twiki/bin/view/Motion/ImproveAlgDrawLocation.
		- Small speed boost to the function draw_textn (Andrew Hamilton and
		Angel Carpintero).
		http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement
		- Avoid Cleanup Segfault. Avoid Cleanup Segfault. Allocates filepath using
		strdup to avoid segfault is target_dir parameter is not supplied in
		motion.conf. Moves out from signal handler the cleanup for pipe and mpipe.
		http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault
		- Changed the configure script so that rpms can be made by normal non-root
		users.
		- Above change in configure script for 64 bit ffmpeg support also implemented
		in the freeBSD configure.
		- Webhttp control interface fixed so it also works in FreeBSD.
		- Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in
		snap4 (Angel Carpintero, Kenneth Lavrsen).
		- Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg
		can increase performance. Especially for machines with very little CPU power.
		It only modifies the configure script. If you do not have the libjpeg-mmx
		the configure script with ignore this and use the standard libjpeg.
		Note that RPMS will be built without this (Peter Holik and Angel Carpintero).
		http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx

		   - Fixed the conf_list[] index in motion.c
		http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
		- http-control: Fixed segfault when motion is restarted from command line
		( kill -s 1 pid_motion ). Improved control code so Motion can Restart and
		Finish 'smoothly'. (Angel Carpintero).
		http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl.
		- Fixed a bug in the http control code that failed to accept a client
		connecting in some systems
	
John Edwards
		- Added the 'pal-nc' norm.

Stephen Farrugia
		- Fixing the division by zero problem.
		This makes motion a lot more stable.

Miguel Freitas
		- Came up with the round robing idea.

Aaron Gage
		- Pointed me to the vid_mmap/int problem when calling SYNC in
		video.c
		
Christophe Grenier
		- Fixed some file descriptor leaks in webcam.c and netcam.c.
		- Renamed the top level global context structure to cnt_list so it can be
		reached from child threads and by above mentioned close_anything_open()
		- Contributed with most of the code for new function in event.c
		close_anything_open() which is called from send_sms, send_mail and
		exec_command in order to prevent file descriptor and open sockets to be
		inherited by the shell causing freezing and instability.
		Code contributed by Christophe Grenier, Christopher Price and
		Kenneth Lavrsen.
		- Change the working directory to / in daemon mode. This way you don't have
		to kill motion to umount the partition from where you start it.
		http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch
		- In netcam-wget header_get() didn't always in add a \0 string terminator.

		http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch
		- Made a pthread fix.
		http://www.lavrsen.dk/twiki/bin/view/Motion/PthreadFixPatch
		- Implemented the conversion of signal to sigaction which should be more
		thread safe. Hopefully this still keeps Motion from making Zombies.
		http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction

Mihnea-Costin Grigore
		- Fixed the oldlayout behaviour of snapshots.
		- Fixed snapshot link extension.
		- Added the snapshot_overwrite option.

Andrew Hamilton
		- Small speed boost to the function draw_textn (Andrew Hamilton and
		Angel Carpintero).
		http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement
		- Added new feature: Double size text. A new config option 'text_double' can
		be set 'on' and this scales the text to double size. Default is off.
		http://www.lavrsen.dk/twiki/bin/view/Motion/TextScalingPatch
		
Peter Holik
		- Netcam First Header patch. If an error with jpeg decompression occured at
		connecting to a mjpeg streaming webcam, this patch skips this jpeg and tries
		to decompress next jpeg up to MAX_HEADER_RETRIES (20).
		http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFirstHeader
		- Small improvement in framerate accuracy.
		http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust
		- Implemented a modified version of the WebcamCompressInMemory so that Motion
		no longer uses the tmpfile() function for buffering the frames of the mjpeg
		stream.
		http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
		- Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg
		can increase performance. Especially for machines with very little CPU power.
		It only modifies the configure script. If you do not have the libjpeg-mmx
		the configure script with ignore this and use the standard libjpeg.
		Note that RPMS will be built without this (Peter Holik and Angel Carpintero).
		http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx
		- Small code cleanup in webcam.c and picture.c and .h for the webcam code
		(Peter Holik and Kenneth Lavrsen).
		- Small speed optimization in the creation of reference frame.

		http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegPatch049
		- Implemented labelling speed patch
		http://www.lavrsen.dk/twiki/bin/view/Motion/LabelingSpeedPatch
		- Improved the signal handling of ctrl-C
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x181426
		- Fixed the ffmpeg code so that Motion also compiles against libavcodec
		build 4754 or later.
		- Fixed a bug in the autobrightness algoritm.
		- RotateBswapFix Patch v 2 including:
		   - cleanup in code comments
		   - fix for __bswap_32 macro collision

		http://www.lavrsen.dk/twiki/bin/view/Motion/RotateBswapFix
		
Matthias Kilian
		- Configure patch which enables configure to find and use a
		dynamic library of ffmpegs libavcodec.so
		
Daniel Ladd
		- Fixed a bug in the rgb2yuv420p function.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x30x011107

Kenneth Lavrsen (Currently project managing Motion)
		- Wrote the excellent Motion Guide. (Jeroen wrote this :-) )
		- Fixed low_cpu to check for a 1sec. maximum wait.
		- Updated manpage for 3.0.0
		- New usertext additions to draw.c
		- Fixed ffmpeg compatibility for ffmpeg 0.4.8
		- Fixed ffmpeg instability problem
		- Fixed "ioctl(VIDIOCGCHAN): Invalid argument" error
		- Changed motion.conf to motion-dist.conf.
		- Changed the parsing of the motion.conf and thread.conf files so
		that spaces are now allowed.
		- Changed the parsing of the user defined on screen display text
		so that you can enclose a string in "" both in config file
		and using the XML-RPC interface. Ie. you can use spaces in the
		text.
		- Changed conf.c so that xml-rpc command motion.conf.write creates
		a much more user friendly motion.conf file.
		- Modified Ian's on screen display putting back the config parameter
		drawtext_changes. If enabled the number of changed pixes are shown
		in the upper right corner of the image.
		- Removed the snap_override feature and reduced the oldlayout to an
		Berkeley mpeg_encode feature only renaming it to
		berkeley_single_directory. Instead the flexible filename
		feature now has oldlayout as default and the "new" directory layout
		specified in the motion.conf file.
		- Motion.conf sequency re-arranged so the important things comes first.
		- Changed names of many options to be more user friendly.
		- Renamed the options for displayed text to text_right, text_left and
		text_changes.
		- Change the parsing of config files so that the argument can be in
		quotation marks (" or ') allowing leading spaces for the text_left
		and text_right options. This means that you can place the text
		anywhere on the picture by using spaces and new lines \n.
		- Fixed problem with strftime based names with event number %v when
		event numbers were higher than 99.
		- Changed motion-control to make a proper output from motion.conf.list.
		- Renamed ffmpeg_timelaps to ffmpeg_timelapse (we change now or never)
		- Corrected man page (\n) (thanks Daniel).
		- Added setting access rights to 644 (755 for configure) when doing
		make dist.
		- Small improvement on xmlrpc-api.html document.
		- Fixed missing init of viddev.frequency causing VIDIOCGCHAN errors.
		XML-RPC changes of threshold and noise_level are now being used as
		long as threshold_tune and noise_level are not enabled.
		- Enabled the round robin feature to also work by changing frequency on
		the same device and same input.
		- Fixed the pre_capture feature so that it also stores the jpegs properly.
		- Fixed the ffmpeg_timelapse feature so that the calculated time is
		correct and the current image is used instead of an old image from
		position 0 in the pre_capture ring buffer.
		- Fixed ffmpeg routines so that also graytone images can be
		pre_captured and used with ffmpeg_timelapse.
		- Fixed the position of the incrementing of shots in the motion_loop
		so that it is correct before any functions use it.
		- Added quite many comments to the code to make it easier to maintain
		(more comments will be added).
		- Removed some old debugging printf's that were displayed in non-quiet
		mode.
		- Changed to snapshot feature from being alarm driven to being timer
		driven. This means that each thread can have its own interval
		value. The XML-RPC motion.action.snapshot still works. The SIGALRM
		method has been changed so that all thread that have the snapshot_interval
		non zero will take a snapshot when being signaled with SIGALRM. A
		negative value for snapshot_interval will activate the SIGALRM trigger
		but not the timing interval.
		- Kenneth Lavrsen changed the enhanced SQL config from single sql_mask
		option to 5 sel_log_ options for more user friendly control.
		- Changed the behaviour of onsave back to original mode where also
		snapshots causes onsave command to be run.
		- Fixed a bug in frequency setting of V4L device.
		- A few lines of code for Dan's improved handling of config strings.
		- Daniel Sterling and Kenneth Lavrsen added a feature that checks for
		two threads having the same webcam_port. If this is the case the last
		thread gets its webcam disabled and a warning message is written
		to console and syslog.
		- Small improvements in messages sent to console and syslog during
		startup of Motion.
		- Fixed the problem with default strings being written to thread
		config files when using the XMLRPC command motion.conf.write.
		- Fixed memory leaks in new ffmpeg code.
		- Changed the ffmpeg code so that mpeg1 files are created using the
		libavcodec method and mpeg4 and msmpeg4 are created using the new
		libavframe method in ffmpeg.
		- Added seconds and frame fields to the database feature.
		- Fixed a small bug related to the filename given for onffmpegclose.
		changed the configure option --with-libavcodec to --with-ffmpeg 
		and updated Guide and man pages and text in code and config file to
		match the new shared library way of using ffmpeg.
		- Added the new fields to the SQL security table camera (thread
		number), text (text_left) and time (timestamp).
		- Simplified the sql functions (1 instead of 3) and ensured that the
		text field is not assigned when text_left is an empty string. This
		allows for the field to be auto defaulted.
		- Added additional error reporting to console.
		- Implemented a new lightswitch feature so that is now triggers lightswitch
		detected based on the percentage of pixels set by the lightswitch option which
		is now an integer instead of a boolean. When lightswitch is detected motion
		skips 5 frames to allow camera to settle.
		- Fixed a bug in the autobrightness function.
		- Fixed a bug in netcam_start() - wrong imgs.size calculation.
		- Removed the obsolete Berkeley mpeg feature.
		- Corrected a small error in the usage help text
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x05x174139
		- Improved the help text for config option night_compensate in docs,
		conf.c, motion man pages and config file.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x103939
		- Implemented a POSIX compliant SIGCHLD signal handler as replacement for
		the traditional signal(SIGCHLD, SIG_IGN) which can cause floods of
		warnings in some RedHat versions. (with Angel Carpintero)
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x26x134906
		- Changed the reporting of the changes of noise detection level so that
		it is only displayed in the console (daemon off) when the always_changes
		option is enabled. (Kenneth Lavrsen)
		- Changed the ffmpeg>0.4.8 = no mpeg1 gcc warning message so that it is
		clear to people that it is information and not an error message.
		- Changed allocation of despeckle buffer to avoid a seg fault when using
		a netcam where the image is wider than defined in motion.conf width.
		- The noise tune value displayed in the upper left corner along with
		number of changed pixels is no longer displayed (was there for debugging).
		- Changed the SIGCHLD handler introduced in snap10 so that it is a shorter
		and faster function. Disabled this handler in the xmlrpc thread as this
		caused unnecessary loops of cpu cycles. Additionally made the code in
		xmlrpc more correct and robust (handling of select()) (Kenneth Lavrsen)
		- Fixed a bug in the timelapse feature. Both the rollover events of the
		timelapse video and timelapse shots could be missed if the CPU load was
		very high or the time was changes by ntp. Motion will now catch up a few
		seconds later if this happens. Also fixed the code for monthly rollover.
		(Kenneth Lavrsen)
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554
		- Small improvement in timelapse feature so that an image is added when
		the new mpeg is created and not waiting till the following timelapse
		(Kenneth Lavrsen).
		- Small improvement so that the rollover happens on the hour and not one
		timelapse past the hour (Kenneth Lavrsen).
		- Fixed a bug in noise tune which was most visible at very low light.
		- Re-arranged many of the const char declarations so that they are always
		before any statements within a block { }. This is to avoid compiler errors
		with older but still used gcc versions such as 2.9.5.
		- Changed the use of %zd to %llu in printf statements of size_t types.
		This is done to avoid compiler errors with older but still used gcc versions
		such as 2.95.
		- Fixed even more gcc 2.95 compiler errors (declarations not at beginning
		of block).
		- Removed a gcc 2.95 compiler warning (netcam.c:1036: warning: variable `pic'
		might be clobbered by `longjmp' or `vfork').
		- The values for cnt->locate and cnt->new_img are now #defines in motion.h
		to enhance code readability.
		- The setting of sql_mask is now only done once per second to save CPU power.
		- Adding checking for conflict between control port and webcam port. Webcam
		port for a thread is disabled if it is set to the same value as the control
		port.
		- Added "motion-http:" prefix to error messages from the http control thread.
		(Kenneth Lavrsen)
		- Added additional error information when connection to MySQL fails.
		- Initiate cnt->event_nr to 1 to avoid code related to end of events and long
		mpeg films to be run during startup of Motion.
		- Added new function in event.c close_anything_open() which is called from
		send_sms, send_mail and exec_command in order to prevent file descriptor and
		open sockets to be inherited by the shell causing freezing and instability.
		Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen.
		- Added new context global cnt_list.control_socket_server set by the httpd
		thread so that the above mentioned close_anything_open() can close open
		control sockets.
		- Threw away the file descripter leak fix from snap 9 because it caused
		more trouble than it fixed. Removed the close_anything_open() and the 
		cnt_list.control_socket_server field. Replaced it all with a simple
		piece of code that all server daemons call when started: setsid() followed
		by for (i=getdtablesize(); i>2; --i) close(i). Dirty and simple.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x21x070534
		- Fixed a bug where rate of fetching picture frames was disturned by
		the signal SIG_CHLD from exec_command programs terminating. The symptom
		was that the number of post_capture frames became inaccurate and motion
		in mpegs did not have constant time between frames.
		- Fixed a bug where motion did not work with gap=1.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x073616
		- Added the feature gap=0 which now also works. It disables gap completely
		so that one single mpeg file is created. You can end the event from the
		remote control interface make movie feature using for example cron.
		This makes Motion close	the mpeg and make a new with event number increased
		by one.
		- Improved the http remote control action features so that makemovie
		and snapshot for thread 0 (all) works on all threads instead of being
		ignored.
		- Moved some code in the beginning of the motion_loop to a position later
		to improve the accuracy of time calculations for the framerate.
		- Improvements of motion.conf help comments including improvements in new
		onxxxx options.
		- Motion Guide refactored completely for 3.2.1 with better web navigation and
		auto generation of pages. Makefile updated so that the Motion TWiki topic
		MotionGuideOneLargeDocument is fetched when updating the guide and making
		releases.
		- Removed the debug_parameter option which had no use. Programmers can still
		use it because the code is only commented out. This change required a small
		update in the code that rewrites motion.conf so that a remote control command
		to write the config files still adds a text header for the thread section at
		the end of motion.conf.
		- Changed the default values for a few options: quiet on, webcam_maxrate 1,
		threshold_tune off, webcam_quality 50.
		- Changed some cosmetics in the way motion.conf is written (space after #).
		- Updated the motion-dist.conf to use default values unless there is a reason
		not to.
		- Fixed a bug in the low_cpu feature where cpu load increased instead of
		decreasing because the framerate calculations were completely wrong. This was
		an old bug introduced in 3.0.1.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x04x24x205933
		- Improved the auto-brightness algoritm. When auto-brightness is enabled
		the brightness option becomes a target value for the brightness level.
		This should also close a bug report.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x26x195358.
		- Made the http control HTML responses nicer to look at as sources and
		therefore easier to debug errors.
		- Code style cleanup of webhttpd.c.
		- Fixed compatibility problem with Palantir. Fixed by making output more
		compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel
		Carpintero. However this fix made Firefox flicker even more than it normally
		does. Final fix which works in both Palantir client, Firefox and Cambozola
		was made by Kenneth Lavrsen. This closes the following bugs:
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307,
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849
		- Added new conversion specifiers: %D (diffs), (noise) %K (motion center x),
		%L (motion center y), %i (locate width x) and %J (locate width y). These
		changes also required a refactoring of the alg_locate code. This change
		is part of the implementation of a generic tracking feature and it enables
		implementing external programs that can perform sinple prediction features.
		http://www.lavrsen.dk/twiki/bin/view/Motion/ExtendReplaceConversionSpecifiersDiscussion
		http://www.lavrsen.dk/twiki/bin/view/Motion/GenericTrackingPatch
		- Fixed a bug in switchfilter which caused motion detection to not work
		when the feature was enabled.
		- Fix for Unknown content type with lumenera cameras
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x06x174416
		- Man page updated. It is now semi-autogenerated in the Motion TWiki
		http://www.lavrsen.dk/twiki/bin/view/Motion/MotionOptionsAlphabeticalManpage
		- Added two new convertion specifiers: %o for threshold and %Q for number
		of labels.
		- Improved the config file description for pre_capture to get people to
		use small values.
		- Major code cleanup concerning signedness of chars all over the code to
		allow compilation with gcc4.0 (like in Fedora Core 4) without any
		errors or warnings. This will probably require that some of the not yet
		included patches will have to be fixed because it it code all over the
		place that has been changed.
		- Changed the configure script so that /usr/lib64 is also searched for
		the presense of ffmpeg (should fix the problem with 64 bit machines).
		- Changed the configure script so that rpms can be made by normal non-root
		users.
		- Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in
		snap4 (Angel Carpintero, Kenneth Lavrsen).
		- Changed all use of localtime to localtime_r which is threadsafe.
		- Modified the WebcamCompressInMemory patch so that Motion now supports the
		mjpeg webcam stream while being setup for saving PPM images.
		http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
		- Major clean-up of code in picture.c and webcam.c so that function names and
		variable names are less confusing. Also added many comments in picture.c.
		- Webcam code commented more.
		- New improved webcam feature. When you set webcam_motion on Motion will now
		stream at 1 fps instead of none. When motion is detected the webcam stream
		increases to the limit set in the config file. This change makes the
		webcam_motion much more interesting. The previous function always ended up
		with clients timing out.
		- Small code cleanup in webcam.c and picture.c and .h for the webcam code
		(Peter Holik and Kenneth Lavrsen)
		- Small code cleanup in motion.c for the variable holding the number of
		microseconds since epoch. The old code worked fine but relied on an integer
		overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen)
		- Fixed bug related to disabled webcam or duplicate webcam port. Error log
		accept(): Socket operation on non-socket continuously written to syslog.
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x01x150922
		- Included a CODE_STANDARD text file to help new developers make patches
		that are easier to integrate without too much manual editing.
		- Changed the 5 second missed camera signal timeout to 30 seconds.
		- Fixed bug where an extra jpeg is saved if you have output_normal=best
		and you stop motion after an event has ended. (Kenneth Lavrsen).
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x05x173526
		- Option switch filter used print_int instead of print_bool when motion.conf
		was saved.

		which is called from send_sms, send_mail and exec_command in order to
		prevent file descriptor and open sockets to be inherited by the shell
		causing freezing and instability. Code contributed by Christophe Grenier,
		Christopher Price and Kenneth Lavrsen.
		- More Netcam Stability Fixes (snap10-post1-6)
		   - Destroy mutexes in netcam_cleanup().
		   - Add reconnection for netcam_start() - this may block other cameras
		     from starting up!.
		   - Added additional defines for reconnect retries.
		   - Change reconnection timeouts to 60 seconds.
		   - Reworked close(sock) in netcam_connect, to insure future changes

		   - Adjusted TIMEOUT_COND_WHICH to 4 seconds.
		http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch
		- More Netcam Stability Fixes (snap11-post1-4) (Christopher Price)
		   - Reworked thread signal/wait conditions, should fix some race conditions.
		   - Use gettimeofday() to determine thread timeouts, results in better accuracy. 
		   - Adjusted condition timeouts to smaller values due to usage of gettimeofday()
		     and rework of thread signal/wait conditions.
		   - Adjusted reconnection retries to 60 (every minute for an hour).

		  the url.
		http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch

Dietz Proepper
		- Always output diff count and output image type selection

rasca
		- A lot of the code in motion.c comes from his vidcat program
		which is part of the w3cam package. (jpeg creation and parts
		of the image capture function)
		(www.hdk-berlin.de/~rasca/w3cam/)
		
Michael Reuschling
		- Fixed bug which caused Motion 3.1.18 fail to save timelapse mpegs when
		setting ffmpeg_timelapse = 1 (fixed by Michael Reuschling)
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x31x211756
		
James A. Russo.
		- Implemented ffmpeg_timelapse_mode feature.
		- Implemented enhanced SQL features. This adds logging of mpeg
		and prediction events to the MySQL/PostgreSQL feature.
		- Replaced the mime file types by a more refined filetype
		scheme that allows more refined control for SQL and other
		future control.

Petter Reinholdtsen
		- Adding the install option to the makefile.
		
Roberto Spadim
		- Fixed compatibility problem with Palantir. Fixed by making output more
		compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel
		Carpintero. However this fix made Firefox flicker even more than it normally
		does. Final fix which works in both Palantir client, Firefox and Cambozola
		was made by Kenneth Lavrsen. This closes the following bugs:
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307,
		http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849
		
Daniel Sterling
		- Studies of the performance of Motion.
		- Night compensation fix.
		- Changed the webcam_port value to 0 in motion-dist.conf to avoid that
		people get segmentation faults when having 2 or more cameras and
		webcam_port not set in the thread config files.
		- Implemented improved handling of config strings. This plugs the memory
		leak when changing string type options via XML-RPC. It also makes the
		memory handling more elegant/optimal and finally it now allows strings
		to be as long as allowed by the environment variable PATH_MAX.
		- Kenneth and Daniel added more comments to motion.c and conf.c.
		- Made the XMLRPC able to handle errors without crashing.
		- Daniel Sterling and Kenneth Lavrsen added a feature that checks for
		two threads having the same webcam_port. If this is the case the last
		thread gets its webcam disabled and a warning message is written
		to console and syslog.
		- Fixed a calculation error in alg_diff_fast().

Tommy Svensson
		- Wrote the original patch for supporting pan/tilt with Logitech
		Quickcam Sphere/Orbit

technolust.cx
		- For hosting motion.technolust.cx

Mark Thomas
		- Created the original thread patch for motion enabling motion to
		watch multiple cameras.

Dirk Traenapp
		- Added the mpeg creation on exit and SIGUSR1, also made the start
		for max_mpeg_time.
		- Found the 'strtok' call that caused motion to crash under RH7.0

Sean Watkins
		- Created a centralized logging function that became event()
		
Joerg Weber	
		- Added the new labeling motion detection feature.
		- Added the new Smartmask feature.
		- Implemented new preview patch (Joerg Weber)
		http://www.lavrsen.dk/twiki/bin/view/Motion/PreviewShotsPatch
		- Implemented an improvement of Smartmask so that the mask is cleared when
		the smart_mask_speed is set from a non-zero to zero
		- Implemented an improvement of noise_tune with smart mask (and probably
		also in general)
		- Added Best Preview Patch
		http://www.lavrsen.dk/twiki/bin/view/Motion/BestPreviewShot
		- Added the new feature Setup Mode (Joerg Weber). This also enables
		much more error messages given to the console when in non-daemon mode
		while still preserving the messages in syslog which are important
		for daemon mode debugging.
		http://www.lavrsen.dk/twiki/bin/view/Motion/SetupModePatch
		- Fixed a bug in noise tune which was most visible at very low light.
		- Improved console output in setup mode. Now also outputs threshold.
		- Improvement in the noise-tune algoritm.
		- Implemented new Generic onxxxx features.
		Function --- Old Option --- New Option
		Start of event (first motion) --- execute --- on_event_start
		End of event (no motion for gap seconds) --- New! --- on_event_end
		Picture saved (jpg or ppm) --- onsave --- on_picture_save
		Movie starts (mpeg file opened) --- onmpeg --- on_movie_start
		Movie ends (mpeg file closed) --- onffmpegclose --- on_movie_end
		Motion detected  --- New! --- on_motion_detected
		http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxCommandsPatch and
		http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxxFeatureDiscussion
		- Fixed small bug when pre_capture buffer is resized during operation.
		- Changed the order of drawing the red mask in setup mode so that the
		smartmask is drawn after the fixed mask.
		- Improved the display of fixed mask. It is now shown as grey instead of
		red. This makes it easier to see the smart mask working when you also have
		a fixed mask.
		- Improved the labelling algoritm so that locate feature and tracking
		features includes all labelled areas above threshold.
		http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch
		

Tristan Willy
		- Wrote Axis 2100 support and added the check for ~/.motion/motin.conf

Folkert Van Heusden
		- Maintained the code from version 3.1.9 till 3.1.12-rc1
		Including features like..
		- Error reporting to syslog.
		- Better memory allocation.
		low_cpu feature extention to configurable frame rate.
		- First work on Logitech Sphere/Orbit tracking.
		- Implemented original pre-record feature. 
		Misc code optimisations
		- Closed 2 memory-leaks (two 'FILE *' were not closed) in the
		webcam-interface.

Robert Eugene Wood
		- Inverse pixels for locate box.

Yieldtech
		- These guys are making a complete linux based security system
		with motion as one of its components.
		- They did the mysql support, new fileformat and the symbolic
		link to the snapshots. You can find them at yieldtech.cz

Christian W. Zuckschwerdt
		- Modified the Makefile and configure files to be more flexible.
