Goby is an Emacs Lisp package to display large fonts and images, which
 can be used as a WYSIWYG presentation tool on GNU Emacs.
 .
 There are two modes, Edit and View, for Goby. Edit mode is implemented
 as a minor mode while View mode as a major mode. The created file (*.gby)
 is just a text, so you can easily handle it.
 .
 To display large fonts, install TrueType font packages. To use images,
 install the netpbm package. To make screen dumps, install the
 imagemagick package.
