2# Generic S3 (Suspend to Mem) test

4# This is the configuration file for sleepgraph. It contains
5# all the tool arguments so that they don't have to be given on the
6# command line. It also includes advanced settings for functions
7# and kprobes. It is run like this
8#
9#    sudo ./sleepgraph.py -config config/example.cfg
