+ Blender Options:
+ -b or --background <file>	Load <file> in background (often used for UI-less rendering)
+ -a or --render-anim 	Render frames from start to end (inclusive)
+ -S or --scene <name>	Set the active scene <name> for rendering
+ -f or --render-frame <frame>	Render frame <frame> and save it.	+<frame> start frame relative, -<frame> end frame relative.
+ -s or --frame-start <frame>	Set start to frame <frame> (use before the -a argument)
+ -e or --frame-end <frame>	Set end to frame <frame> (use before the -a argument)
+ -j or --frame-jump <frames>	Set number of frames to step forward after each rendered frame
+ -o or --render-output <path>	Set the render path and file name.	Use // at the start of the path to
+ render relative to the blend file.	The # characters are replaced by the frame number, and used to define zero padding.
+ ani_##_test.png becomes ani_01_test.png
+ test-######.png becomes test-000001.png
+ When the filename does not contain #, The suffix #### is added to the filename	The frame number will be added at the end of the filename.
+ eg: blender -b foobar.blend -o //render_ -F PNG -x 1 -a
+ //render_ becomes //render_####, writing frames as //render_0001.png//
+ -E or --engine <engine>	Specify the render engine	use -E help to list available engines
+
+ Format Options:
+ -F or --render-format <format>	Set the render format, Valid options are...
+ TGA IRIS JPEG MOVIE IRIZ RAWTGA
+ AVIRAW AVIJPEG PNG BMP FRAMESERVER	(formats that can be compiled into blender, not available on all systems)
+ HDR TIFF EXR MULTILAYER MPEG AVICODEC QUICKTIME CINEON DPX DDS
+ -x or --use-extension <bool>	Set option to add the file extension to the end of the file
+ -t or --threads <threads>	Use amount of <threads> for rendering in background	[1-64], 0 for systems processor count.
+
+ Animation Playback Options:
+ -a <options> <file(s)>	Playback <file(s)>, only operates this way when not running in background.
+ -p <sx> <sy>	Open with lower left corner at <sx>, <sy>
+ -m		Read from disk (Don't buffer)
+ -f <fps> <fps-base>		Specify FPS to start with
+ -j <frame>	Set frame step to <frame>
+
+ Window Options:
+ -w or --window-border 	Force opening with borders (default)
+ -W or --window-borderless 	Force opening without borders
+ -p or --window-geometry <sx> <sy> <w> <h>	Open with lower left corner at <sx>, <sy> and width and height as <w>, <h>
+ -con or --start-console 	Start with the console window open (ignored if -b is set)
+
+ Game Engine Specific Options:
+ -g Game Engine specific options
+ -g fixedtime		Run on 50 hertz without dropping frames
+ -g vertexarrays		Use Vertex Arrays for rendering (usually faster)
+ -g nomipmap		No Texture Mipmapping
+ -g linearmipmap		Linear Texture Mipmapping instead of Nearest (default)
+
+ Misc Options:
+ -d or --debug 	Turn debugging on
+ * Prints every operator call and their arguments
+ * Disables mouse grab (to interact with a debugger in some cases)
+ * Keeps python sys.stdin rather than setting it to None
+ --debug-fpe 	Enable floating point exceptions
+ --debug-ffmpeg 	Enable debug messages from FFmpeg library
+ --debug-libmv 	Enable debug messages from libmv library
+
+ --factory-startup 	Skip reading the "startup.blend" in the users home directory
+
+ --env-system-datafiles 	Set the BLENDER_SYSTEM_DATAFILES environment variable
+ --env-system-scripts 	Set the BLENDER_SYSTEM_SCRIPTS environment variable
+ --env-system-python 	Set the BLENDER_SYSTEM_PYTHON environment variable
+
+ -nojoystick 	Disable joystick support
+ -noglsl 	Disable GLSL shading
+ -noaudio 	Force sound system to None
+ -setaudio 	Force sound system to a specific device	NULL SDL OPENAL JACK
+
+ -h or --help 	Print this help text and exit
+
+ -y or --enable-autoexec 	Enable automatic python script execution, (default)
+ -Y or --disable-autoexec 	Disable automatic python script execution (pydrivers & startup scripts)
+
+ -P or --python <filename>	Run the given Python script (filename or Blender Text)
+ --python-console 	Run blender with an interactive console
+ --addons 	Comma separated list of addons (no spaces)
+ -v or --version 	Print Blender version and exit
+ -- 	Ends option processing, following arguments passed unchanged. Access via python's sys.argv
+ Other Options:
+ /? 	Print this help text and exit (windows only)
+ --debug-python 	Enable debug messages for python
+ --debug-events 	Enable debug messages for the event system
+ --debug-wm 	Enable debug messages for the window manager
+ --debug-all 	Enable all debug messages (excludes libmv)
+ --debug-value <value>	Set debug value of <value> on startup
+
+ --debug-jobs 	Enable time profiling for background jobs.
+ --verbose <verbose>	Set logging verbosity level.
+ -R 	Register .blend extension, then exit (Windows only)
+ -r 	Silently register .blend extension, then exit (Windows only)
+ Argument Parsing:	arguments must be separated by white space. eg
+ "blender -ba test.blend"
+ ...will ignore the 'a'
+ "blender -b test.blend -f8"
+ ...will ignore 8 because there is no space between the -f and the frame value
+ Argument Order:
+ Arguments are executed in the order they are given. eg
+ "blender --background test.blend --render-frame 1 --render-output /tmp"
+ ...will not render to /tmp because '--render-frame 1' renders before the output path is set
+ "blender --background --render-output /tmp test.blend --render-frame 1"
+ ...will not render to /tmp because loading the blend file overwrites the render output that was set
+ "blender --background test.blend --render-output /tmp --render-frame 1" works as expected.
+
+ Environment Variables:
+ $BLENDER_USER_CONFIG      Directory for user configuration files.
+ $BLENDER_USER_SCRIPTS     Directory for user scripts.
+ $BLENDER_SYSTEM_SCRIPTS   Directory for system wide scripts.
+ $Directory for user data files (icons, translations, ..).
+ $BLENDER_SYSTEM_DATAFILES Directory for system wide data files.
+ $BLENDER_SYSTEM_PYTHON    Directory for system python libraries.
+ $TMP or $TMPDIR           Store temporary files here.
+ $SDL_AUDIODRIVER          LibSDL audio driver - alsa, esd, dma.
+ $PYTHONHOME               Path to the python directory, eg. /usr/lib/python.
