Sometimes you have a built tree, but you can't remember the exact flags you used to build it. If you re-invoke SCons with different flags, you may end up rebuilding the world. SCons could easily write a file like build/last.invocation which would contain the command line of the most recent invocation. Re-running the contained command should always be a no-op if no source changes have been made.
