This document discusses AdaCore's factory for releasing GNAT Pro compiler versions and handling customer wavefront requests. It provides an overview of the architecture used to continuously build and deliver GNAT Pro releases and wavefronts across many platforms and environments through an automated system. The architecture leverages both internal and open source tools to manage source code, scheduling, building, testing, and delivery of releases on a daily basis.
