Usage: $0 [-d] [-x <bootstrap xml>] [-p<path to FWD libraries>] [-f<slf4j-impl.jar file>] [-n<path to native spawner>] [-c<srv-certs.store file>] [-t<postbuild.sh tool>]

Position spawner as needed by current configuration

Where:

       -d = dryrun (just display commands)

       -x <bootstrap xml> = use <bootstrap xml> as the bootstrap file (def=server.xml)

       -p = Location of FWD libraries p2j.jar and fwd-slf4j.jar (if no -f specified). \"FWD_LIB\" will be used as a fallback if default is not valid. (def=${p2j_lib})

       -f = Location of file to be placed in slf4j-impl.jar destination (def=fwd-slf4j.jar in -p location or FWD_LIB)

       -n = Location of built native spawner (def=${spawn_prog}, unless -p specified, which will change the default location)

       -c = Location of srv-certs.store file (def=${srv_certs})

       -t = Location of postbuild.sh tool (def=${postbuild}, unless -p specified, which will change the default location)

 -? or -h or --help = show usage.
