rogue [UNIX] n. A Dungeons-and-Dragons-like game using character graphics, written under BSD UNIX and subsequently ported to other
UNIX systems. The original BSD `curses(3)' screen-handling
package was hacked together by Ken Arnold to support
`rogue(6)' and has since become one of UNIX's most important
and heavily used application libraries. Nethack, Omega, Larn, and
an entire subgenre of computer dungeon games all took off from the
inspiration provided by `rogue(6)'. See also nethack.
