38GNU Emacs is an extensible, customizable text editor — and more.
39At its core is an interpreter for Emacs Lisp, a dialect of the
40Lisp programming language with extensions to support text editing.

73 via Hiragana->Kanji conversion (\'set-input-method japanese\'). This
74 dictionary is huge, so huge that emacs won\'t be able to load it on systems
