libaunit21 binary package in Ubuntu Mantic arm64

 AUnit is a set of Ada packages based on the xUnit family of unit test
 frameworks. It's intended as a developer's tool to facilitate
 confident writing and evolution of Ada software. It is purposely
 lightweight, as one of its main goals is to make it easy to develop
 and run unit tests, rather than to generate artifacts for process
 management. The framework supports easy composition of sets of unit
 tests to provide flexibility in determining what tests to run for a
 given purpose.
 .
 This package contains the runtime shared library.
