If you follow the steps in Section Quick Start, above, you can skip this section.
It is possible to look up the documentation for any built-in or library predicate from within Emacs (using C-c ? or the menu). For this to work Emacs must be told about the location of the `info'-files that make up the documentation.
The default location for the `info'-files are <prefix>/lib/sicstus-4.0.0/doc/info/ on UNIX platforms and C:/Program Files/SICStus Prolog 4.0.0/doc/info/ under Windows.
Add the following to your ~/.emacs file, assuming INFO is the path to the info files, e.g. C:/Program Files/SICStus Prolog 4.0.0/doc/info/
(setq Info-default-directory-list
(append Info-default-directory-list '("INFO")))
for GNU Emacs, or
(setq Info-directory-list
(append Info-directory-list '("INFO")))
for XEmacs. You can also use M-x customize-group <RET> info <RET> if your Emacs is new enough. You may have to quit and restart Emacs for these changes to take effect.
