At its core is an interpreter for Emacs Lisp, a dialect of the 
Lisp programming language with extensions to support text editing.

$(call Package/emacs/Default/description)
 This package contains the japanese dictionary used to input japanese Kanji 
 via Hiragana->Kanji conversion (\'set-input-method japanese\').  This
 dictionary is huge, so huge that emacs won\'t be able to load it on systems
 with 32MB or fewer RAM.

endef

define Package/emacs-el/description
$(call Package/emacs/Default/description)
 This package contains the Lisp source files of Emacs that can queried via
 C-h f in case provided documentation of an Emacs function is insufficient.
