documentation:

--- I/O action which reads an AbstractCurry program from a file in ".acy"
--- format. In contrast to <CODE>readCurry</CODE>, this action does not parse
--- a source program. Thus, the argument must be the name of an existing
--- file (with suffix ".acy") containing an AbstractCurry program in ".acy"
--- format and the result is a Curry term representing this program.
--- It is currently predefined only in Curry2Prolog.
