"""\
flocktest - shepherd script for the GPSD test flock
usage: flocktest [-d subdir] [-k key] -v [-x exclude] [-?]
The -? makes flocktest prints this help and exits.
The -k mode installs a specified ssh public key an all machines
Otherwise, the remote flockdriver script is executed on each machine.
The -d option passes it a name for the remote test subdirectory
The -v option shows all ssh commands issued and runs flockdriver with -x set.
The -x option specifies a comma-separated list of items that are
either remote hostnames or architecture tags. Matching sites are
excluded. You may wish to use this to avoid doing remote tests that
are redundant with your local ones.
If you have a .flocktest file, it is interpreted as a set of
attribute/value pairs, one per line separated by '='. The following
attributes are recognized:
subdir = a default test directory name (-d)
exclude = a default exclusion set (-x)
If you do not specify a subdirectory name either with -d or in the
.flocktest file, the value of $LOGNAME will be used.
