Using the delivered mk to rebuild mk. You should be able to use the delivered executable of mk tobuild a new executable.  This may be of particular intereston Windows NT/Win95 where the path of the shell programcan be hard-coded by changing the variable named "shell"near the beginning of source file Nt.c. Mk uses the regular expression library, so buildthe program as follows: 1.  ensure that ../../mkconfig contains the proper system definitions 2.  ensure that the system libraries lib9, libbio, and libregexp have	been built.  you can do this by hand by changing to ../lib9,	../libbio, and ../libregexp and doing "mk nuke" and a "mk install"	in each. 3. in this directory	mk nuke	mk install 4. on NT/Win95 the executable must be installed by hand because the current	executable is locked down while it is executing: 	mv obj.out ../../Nt/386/bin/mk.exe
