libmirclient-debug-extension1 0.24.0+16.10.20160815.3-0ubuntu2 (arm64 binary) in ubuntu yakkety

 Mir is a display server running on linux systems, with a focus on efficiency,
 robust operation and a well-defined driver model.
 .
 This package contains both a shared library containing the client side of
 various optional debugging interfaces and the development headers required
 to use them.
 .
 This is primarily useful for developing Mir servers, low-level client
 toolkits, or for automated testing in constrained environments.
 .
 Not all Mir servers have the capability to service these APIs; end-user
 applications SHOULD NOT depend on this library.
