“AdaBasis, an acronym for the German phrase ‘Bibliothek anwendungsbezogener Ada Software-Komponenten in Stuttgart,’ is a repository of (mostly) free Ada Software, presented in a way that is (hopefully) easy to use and allows flexible access and effective searching. The software in this repository is based mainly on the PAL and is still extending. It is presented in a hierarchical manner, separated in different application domains, and, for some domains, with an additional searching facility.”
