Wikipedia:Articles for deletion/Doublefuck programming language
This article seems totally non-notable. About 50 google results, and about 6 not related to Wikipedia. It would appear the only information there is (or could possibly ever be) about this language is: "It's Brainfuck but with two buffers, see Brainfuck for more information."
Note that this was apparently listed on VfD in late September/early August 2004, but I could find no record of its discussion.CXI 16:06, 22 Dec 2004 (UTC)
