GNAT is a free, high-quality, complete compiler for Ada, integrated into the
GCC compiler system; the front-end and run-time are written in Ada. GNAT
supports Ada ISO Standards from 1985 to 2022.

Ada was designed for embedded and real-time systems, its features include:
 * Strong static typing
 * Modular programming (via the package)
 * Encapsulation
 * Readability
 * Optional run-time checking
 * Concurrency (via tasks and protected objects), and message passing, as
   constructs in the language itself
 * Generics

Ada is designed for "Programming in the large", it suits rapid development, and
directly supports structured, object-oriented, generic, distributed and
concurrent programming paradigms. Ada is considered a Design Programming
Language, as a result of the expressive abstractions and features that informed
it's design, and provided to the user. Its expressiveness allows users to
clearly represent design solutions modeled on their problem domain, in
accessible language.
