=item B<-V>, B<--version>

=item B<-h>, B<--help>

Displays a brief usage message

=item B<--man>

Displays the man page

=item B<-s> I<server_url>, B<--server>=I<server_url>

The URL of the WebService::TestSystem server to connect to.  By default,
it uses 'http://localhost:8081'.

=item B<-r> I<resource_uri>, B<--resource>=I<resource_uri>

The URI of the service provided by the server.  By default, it uses
'http://www.osdl.org/WebService/TestSystem'.  Users should not typically
need to alter this setting.

=item B<-f> I<authfile>, B<--authfile>=I<authfile>

The path and filename for a file to contain the authorization
credentials provided by the server.  This is a binary file containing a
ticket consisting of the username and a server-provided signature.  By
default, this will be placed in the user's home directory.  Note that if
you override this setting, you will need to also specify the file
location to any other tools that rely on the file for invoking
authenticated operations on the server.
