    (description "Ada/Ed is a translator-interpreter for Ada 83.  It's intended
primarily as a teaching tool and lacks the capacity, performance, and robustness
of other contemporary or modern-day Ada compilers.

Ada/Ed was the first Ada compiler to pass the @acronym{ACVC, Ada Compiler
Validation Suite} version 1.7 but fails many newer tests and is not a validated
Ada system.  Being an interpreter, it does not implement most representation
clauses, and thus does not support systems programming close to the machine
level.")
