86usage: $(basename $0) [ <options> ] <ip-address> [ <count> ]
87Options:
88  --output_dir <directory>
89  --o <directory>       Specify output directory for results
90
91  --board <BOARDNAME>   name of board we are testing (e.g. daisy)
92
93  --[no]keep_logs
94  -k                    Keep [don't keep] autotest log files
95Summary:
96  Run the platform_BootPerfServer autotest, and store results in the
97  given destination directory.  The test target is specified by
98  <ip-address>.
99
100  By default, the test is run once; if <count> is given, the test is
101  run that many times.  Note that the platform_BootPerfServer test
102  reboots the target 10 times, so the total number of reboots will
103  be 10*<count>.
104
105  If the destination directory doesn't exist, it is created.  If the
106  destination directory already holds test results, additional
107  results are added in without overwriting earlier results.
108
109  If no destination is specified, the current directory is used,
110  provided that the directory is empty, or has been previously used
111  as a destination directory for this command.
112
113  By default, only a summary subset of the log files created by
114  autotest is preserved; with --keep_logs the (potentially large)
115  autotest logs are preserved with the test results.
