-B - don't build. Will pull the sources and show you the nanobsd.sh invocation
     string instead. 
-f - if not specified, will pass either -b (if prebuilt) to nanobsd.sh, or
     nothing if not prebuilt. If specified once, force a
     buildworld / buildkernel (passes -n to nanobsd). If specified twice, this
     won't pass any options to nanobsd.sh, which will force a pristine build.
-j - number of make jobs to run; defaults to $MAKE_JOBS.
-u - force an update via csup (warning: there are potential issues with
     newly created files via patch -- use with caution).
