# Makefile for Fortran library and programs to manipulate SIR files
# written by D. Long Mar. 2017
#
# be sure to manually edit lib/SIR.nc to reflect machine/compiler type
# prior to running.  Also, check to compile statement below to include
# or not include the SIREZ routines
#

#
# compile flags should allow long source lines and initialized static variables
