Welcome to OpenDDS version $ver
Options for this script are listed below, with the default behavior described
in parenthesis after the option description.
Boolean options can take the form "--opt" or "--no-opt", the more commonly
needed one (the one that changes the default behavior) is shown below.
Options that require arguments are shown as "--opt=VAL". Options with optional
arguments are shown as "--opt[=VAL]". Options that can be repeated with
cumulative effect are shown with a trailing "...". Some third-party
optional dependencies can be automatically located if they are installed in the
expected locations (see entries below marked with "system pkg"). In those
cases, specify the option as --opt without an = to enable the corresponding
feature in OpenDDS and use the default installation location.
