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.
