libmirclient-debug-extension-dev 0.26.3+17.10.20170526.3-0ubuntu2 (ppc64el binary) in ubuntu artful

 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.
 .
 This package contains the development headers required to develop against
 the debug extensions.
