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