#
# Generic S3 (Suspend to Mem) test
#
# This is the configuration file for sleepgraph. It contains
# all the tool arguments so that they don't have to be given on the
# command line. It also includes advanced settings for functions
# and kprobes. It is run like this
#
#    sudo ./sleepgraph.py -config config/example.cfg
#
