This script runs every build as a hook. If it detects that the build should
be clobbered, it will touch the file <build_dir>/.landmine_triggered. The
various build scripts will then check for the presence of this file and clobber
accordingly. The script will also emit the reasons for the clobber to stdout.
A landmine is tripped when a builder checks out a different revision, and the
diff between the new landmines and the old ones is non-null. At this point, the
build is clobbered.
