# This is an example configuration file for p2p_ALOS.csh 
#
# all the comments or explanations are marked by "#" 
# The parameters in this configuration file is distinguished by their first word so 
# user should follow the naming of each parameter.
# the parameter name, = sign, parameter value should be separated by space " ". 
# leave the parameter value blank if using default value. 
# 
# DO NOT DIRECTLY COMMENT PARAMTERS WITH "#" !!!
# THIS WILL DUPLICATE PARAMETERS AND CAUSE TROUBLE !!!
