Usage: gdb_mbuild.sh [ <options> ... ] <srcdir> <builddir>

 Options:

   -j <makejobs>  Run <makejobs> in parallel.  Passed to make.

                  On a single cpu machine, 2 is recommended.

   -k             Keep going.  Do not stop after the first build fails.

   --keep         Keep builds.  Do not remove each build when finished.

   -e <regexp>    Regular expression for selecting the targets to build.

   -f             Force rebuild.  Even rebuild previously built directories.

   -v             Be more (and more, and more) verbose.

 Arguments:

   <srcdir>       Source code directory.

   <builddir>     Build directory.

 Environment variables examined (with default if not defined):
