# Shave and a Haircut
# (c) 2019 Epic Games
# US Patent 6720962

#  Returns the value of a V-Ray build configuration variable for a given version of Maya
#
#	getMayaConfig <mayaVersion> <variable>
#
#  The available config variables are:
#
#	makefileRoot	- the OS-specific portion of the Makefile names used to build the V-Ray
#			  plugins and shaders for this version of Maya. (We should do away with
#			  this at some point and use the 'osTag' value for the Makefile names.)
#			  e.g. 'osxMavericks'
#
#	osTag		- string used to identify different versions of the operating system
#			  in file paths.
#			  e.g. 'mavericks'
#
#	versionDB	- path to the file containing the list of V-Ray versions that Shave
#			  supports for each version of Maya.
#			  e.g. vrayPlug/supportedVrayVersions.txt
#
#	versionRanges	- list of V-Ray version ranges supported by this version of Maya
#			  e.g. '3.10.00/3.10.99 3.60.00/3.60.99'
#
#	versions	- same as 'versionRanges' but only giving the starting versions of the
#			  ranges
#			  e.g. '3.10.00 3.60.00'
#
#	versionTags	- list of the shortened version numbers Chaos uses to tag various files
#			  e.g. '36 40'
#
