# but it would mean that rebuilding the tools in this directory in another
# grade (e.g. to enable debugging) would take several minutes. To avoid such
# delays, we copy across the source files of the mdbcomp library. The copied
# .m files, and the .m files that natively reside in this directory, can be
# recompiled in a different grade much more quickly than that.
