# gmake makefile for MMM95 model module 
#
# NOTE Must use gmake not make.
# The user must set the environmental variable "CPU" to be
# one of the following:
#
# FUJITSU  for the Lahey Fujitsu F90/F95 compiler
# IBM      for the standard compiler on IBM/AIX workstations
# SOL      for the standard compiler on Sun Solaris workstations
# SGI      for the standard compiler on SGI IRIX workstations
# DEC      for the standard compiler on DEC alpha workstations
# HP       for the standard compiler on Hewlett Packard workstations
#
#       For example, in the Bourne shell on an SGI workstation, type:
#
#  export CPU=SGI
#
#       If you are using the C-shell on an SGI workstation, type
#
#  setenv CPU SGI
#
# Use `gmake clean' to remove all binaries.
#
# The MMM95 transport model has been used ONLY in DOUBLE PRECISION
# with the precision set by flags in the makefile
#
# Glenn Bateman and Arnold Kritz, Lehigh University

#
# environment variable CPU is used to set platform-dependent make variables.
