To run ALE, it is only necessary to type the following query:
| ?- compile( File).where File is the file in which the file ale.pl resides. SWI Prolog users must type:
| ?- consult( File).Note that File does not have to be local to the directory from which Prolog was invoked.
In SICStus Prolog, when ALE is loaded, it turns on Prolog character escapes. ALE will not be able to generate code properly during compilation without this.
