Ran it in single user mode to test all of my RAM and it worked great. Very easy to use so long as you follow the instructions, though some familiarity with the command line helps. My only suggestions, to make this easier for the less technically-inclined:

- Package it better, either as an installer or a single package (.app), rather than just a confusing folder of files.

- The documentation could be clearer. I'd include as-simple-as-possible step-by-step instructions first (including how to start in single user mode), with a separate section on advanced options. Put the release notes after the instructions.
