#TODO:
#~ Stats for .RAW files.
#~ Integrate anti-vertical banding. May require being able to use multiple darkframe files.
#~ Atadenoise integration.

#~ Better Preview:
#~ --> A different module (like -e) for live viewing of footage, under convmlv settings. Danne is working on this :).

#BUG: Relative OUTDIR makes baxpixel generation fail if ./mlv2badpixels.sh doesn't exist. Fixed on Linux only.
#BUG: Colorspace Bug Affecting all but EXR output.

	  --> How to: Record 5 sec w/lens cap on & same settings as footage. Pass MLV in here.
	  --> If the file extension is '.darkframe', the file will be used as the preaveraged dark frame.
	
	-R <path>		dark_out - Specify to create a .darkframe file from passed in MLV.

	-Y			Python Deps - Lists Python dependencies. Works directly with pip.
	  -->Install (Linux): sudo pip3 install $ (./convmlv -Y)
	
	-M			Manual Deps - Lists manual dependencies, which must be downloaded by hand.
	  --> There's no automatic way to install these. See http://www.magiclantern.fm/forum/index.php?topic=16799.0 .
	
CONFIG FILE:
	You do not need to type in all the arguments each time: Config files, another way to specify options, can save you time & lend
	you convenience in production situations.
	
	GLOBAL: $HOME/convmlv.conf
	LOCAL: Specify -C/--config.

	Some options have an uppercased VARNAME, ex. OUTDIR. In a convmlv config file, you can specify this option
	in the following format, line by line:
		<VARNAME> <VALUE>
		
	If the value is a true/false flag, simply specifying VARNAME is enough. Otherwise, normal rules for the value applies.
	
	Options override each other as such:
	-LOCAL overrides GLOBAL config.
	-Passed arguments override both configs.
	-Lines starting with # are comments.
	-Name a config using the VARNAME: CONFIG_NAME <name>
	
	
	File-Specific Block: A LOCAL config file lets you specify options for specific input names:
		/ <TRUNCATED INPUTNAME>
			...specify options
		*
		
	$(echo -e "\e[1mFile-Specific Blocks override all other options.\e[0m") This allows one to create
	a single config file to batch-develop several input files/folders at once, after deciding how each one should
	look/be configured individually.
	
	Notes on Usage:
	-You must use the truncated (no .mlv or .raw) input name after the /.
	-No nested blocks.
	-Indentation by tabs or spaces is allowed, but not enforced.
