  30 # Script to build the MDB modules present in a workspace against the set of
  31 # include files saved in an MDB "root" (created with mkroot.sh), and install
  32 # resulting modules into this tree so that it can be used as the argument
  33 # to ``mdb -R'' or by mdb's auto-detect code, used by the mdb.sh wrapper.
  34 # We use the ``make dmods'' target to do the build -- this is equivalent to
  35 # make install, but does not build the debugger itself, and pass a special
  36 # define (_MDB_BLDID) into the compilation environment so that the module
  37 # source can detect the various changes in header files, etc.  This is only
  38 # used for module source kept on mdb.eng that needs to compile against
  39 # legacy builds of the operating system.
