##########################

# z264 has several dependencies (mediainfo, rmtrash, ffmpeg, SublerCLI, and HandBrakeCLI)
# need logic here to check for dependencies
# and if missing, prompt user for how to install missing dependencies (binary or source)
# for now, installation is manual
# uncomment appropriate section to install, but *must* re-comment these sections to use z264)
# unfinished: 	xcode section, so if you can manually install xcode, the macports section should 
# 				build the dependencies from source. HandBrakeCLI binary is most recent version.
#				background_transcoder functions well, yet is still evolving; pay attention to the
#				unfinished ramdisk section, as it is currently manual as well. Double check the
#				command definitions for all dependecies and adjust accordingly.
