RTFM: /R-T-F-M/ imp. [Unix] Abbreviation for `Read The Fucking
Manual'. 1. Used by gurus to brush off questions they consider
trivial or annoying. Compare Don't do that then!. 2. Used when
reporting a problem to indicate that you aren't just asking out of
randomness. "No, I can't figure out how to interface Unix to my
toaster, and yes, I have RTFM." Unlike sense 1, this use is
considered polite. See also FM, RTFAQ, RTFB, RTFS, STFW,
RTM, all of which mutated from RTFM, and compare UTSL.
