[Code]
This section is devoted to showing how ALE programs can actually
be compiled. ALE was developed to be run with a Prolog
compiler, such as SICStus Prolog's. An SWI port of ALE is
available, which also has a less extensive compilation phase. We
strongly recommend SICStus Prolog. SWI Prolog does not scale up well
to large-sized grammars. The local systems administrator should be
able to provide help on running Prolog. This documentation only
assumes the user has figured out how to run Prolog as well as write
and edit files. It is otherwise self-contained.
