:RTFM: /R-T-F-M/ [UNIX] imp. Acronym for `Read The Fucking
Manual'. 1. Used by {guru}s 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}, {RTM}, all of which mutated
from RTFM, and compare {UTSL}.
