# Variable naming conventions:
# TARGET_*:	A build system variable specifying a property for building for
#			the target platform (usually Haiku). E.g. TARGET_CC specifies the
#			compiler when building a target for the target platform.
# HOST_*:	A build system variable specifying a property of the platform
#			hosting the build. E.g. HOST_CC specifies the compiler when
#			building a target for the host platform (a build tool for
#			instance).
# HAIKU_*:	A build system variable specifying a build system property. Usually
#			directory paths and the like.
