# To compile BusyBox without touching the original sources
# (as might be interesting for multi-target builds), create
# an empty directory, cd into it, and run this program by
# giving its explicit path (kind of like how you would run
# configure, if BusyBox had one). Then you should be ready
# to "make". Files in the build tree, in particular Config.h,
# will override those in the pristine source tree.
#
# if you use a ? in your path name, you lose.
