description     The GNU Emacs text editor (command line only)
long_description \
    GNU Emacs is a self-documenting, customizable, extensible real-time \
    display editor. Users new to Emacs will be able to use basic        \
    features fairly rapidly by studying the tutorial and using the      \
    self-documentation features. Emacs also has an extensive            \
    interactive manual browser. It is easily extensible since its       \
    editing commands are written in Lisp.
