Mono CLI (.NET) runtime
 Mono is a platform for running and developing applications based on the
 ECMA/ISO Standards. Mono is an open source effort led by Novell.
 Mono provides a complete .NET CLR including compiler and runtime, which can
 produce and execute CIL bytecode (assemblies), and a .NET class library.
 .
 mono is a metapackage containing dependencies for the runtime of Mono.
 If you do not need all of them (or try to work around X11
 dependencies), install the core packages manually: mono-jit, mono-mcs or
 mono-utils.
