 Building Faster
 ===============
 
-By default, buildman executes 'make mrproper' prior to building the first
-commit for each board. This causes everything to be built from scratch. If you
-trust the build system's incremental build capabilities, you can pass the -I
-flag to skip the 'make mproper' invocation, which will reduce the amount of
-work 'make' does, and hence speed up the build. This flag will speed up any
-buildman invocation, since it reduces the amount of work done on any build.
