Assuming the Emacs interface for SICStus Prolog has been installed in the default location, inserting a single line in your ~/.emacs will make Emacs use the SICStus Prolog mode automatically when editing files with a `.pl' extension. It will also ensure Emacs can find the SICStus executables and on-line documentation, etc.
Note to Windows users: ~/.emacs denotes a file .emacs in whatever Emacs considers to be your home directory. See `GNU Emacs FAQ For Windows 98/ME/NT/XP and 2000' at http://www.gnu.org/software/emacs/windows/ntemacs.html, for details.
Under UNIX, assuming SICStus 3.12.10 was installed in /usr/local/, add the following line:
(load "/usr/local/lib/sicstus-3.12.10/emacs/sicstus_emacs_init")
Under Windows, assuming SICStus 3.12.10 was installer in C:\Program Files\SICStus Prolog 3.12.10\, add the following line:
(load "C:/Program Files/SICStus Prolog 3.12.10/emacs/sicstus_emacs_init")
No other configuration should be needed to get started. If you want to customize things, look in the sictus_emacs_init.el file and the rest of this section.
