description An Emacs mode for unifying Common Lisp development

long_description    \
    SLIME extends Emacs with new support for interactive \
    programming in Common Lisp. The features are \
    centred around `slime-mode', an Emacs minor-mode \
    that complements the standard `lisp-mode'. While \
    `lisp-mode' supports editing Lisp source files, \
    `slime-mode' adds support for interacting with a \
    running Common Lisp process for compilation,\
    debugging, documentation lookup, and so on.
