  27 Usage: gdb_mbuild.sh [ <options> ... ] <srcdir> <builddir>
  28  Options:
  29    -j <makejobs>  Run <makejobs> in parallel.  Passed to make.
  30                   On a single cpu machine, 2 is recommended.
  31    -k             Keep going.  Do not stop after the first build fails.
  32    --keep         Keep builds.  Do not remove each build when finished.
  33    -e <regexp>    Regular expression for selecting the targets to build.
  34    -f             Force rebuild.  Even rebuild previously built directories.
  35    -v             Be more (and more, and more) verbose.
  36  Arguments:
  37    <srcdir>       Source code directory.
  38    <builddir>     Build directory.
