I totally agree with Gregor. The -J switch might give us a hint that the
files /on the command line/ must be recompiled, but it still doesn't make
it easier to find out what other files are needed in the application. One
purpose of Bud, and I assume Rebuild, is to allow the coder to just enter
one name on the command line and get all the other required files magically
included in the compilation process. The alternative is to require the
coder to maintain makefiles and/or type every required file onto the
command line.
