I had snipped the rest.  Here is the whole thing:
# makefile

# This file will build a boot strap client. 

SHELL=/bin/bash
AWK=/bin/awk

# Define public key based on varible input
ifeq "${NETWORK}" "172_16_0_0"
        PUBLICKEY=root-172.16.48.66.pub
endif
ifeq "${NETWORK}" "192_168_0_0"
        PUBLICKEY=root-192.168.81.43.pub
endif
ifeq "${NETWORK}" "10_208_66_0"
        PUBLICKEY=root-10.208.66.59.pub
        NETWORK=172_16_0_0
endif
