ABSTRACT_aarm = The Annotated Ada Reference Manual, ISO/IEC \
 8652:$(ISO_$(y))(E). It contains the entire text of the Ada $(y) \
 standard, plus various annotations. It is intended primarily for \
 compiler writers, validation test writers, and other language \
 lawyers. The annotations include detailed rationale for individual \
 rules and explanations of some of the more arcane interactions among \
 the rules.
