     components, including pybindgen, NSC, regression testing traces,
     along with cloning a ns-3 repository.  By default, the main
     development ns-3 branch, ns-3-dev, will be cloned, but it can be
     overridden via the -n command line option.  For example,
     
       ./download.py -n craigdo/ns-3-tap

     will clone the repository http://code.nsnam.org/craigdo/ns-3-tap
     into the allinone directory.

     By default, the regression traces will be cloned from the usual
     http://code.nsnam.org/ns-3-dev-ref-traces into a directory
     ns-3-dev-ref-traces in the allinone directory.  You can override
     this using the -r command line option.  For example,

       ./download.py -n craigdo/ns-3-tap -r craigdo/ns-3-tap-ref-traces

     will clone the repository http://code.nsnam.org/craigdo/ns-3-tap
     into the allinone directory and also clone the reference traces
     from the http://code.nsnam.org/craigdo/ns-3-tap-ref-traces repo.
