# The target system is characterized by the following macros imported from
# the environment.
#
#	OS	      - gives the class of operating system
#	OSRELEASE     - optionally gives the particular release of the OS above.
#	OSENVIRONMENT - optionally gives the environment under which the above
#			OS is in use.

# For valid values for the above macros consult the readme/* files or type
# 'make' by itself to get a summary of what is available.
