mono-runtime-sgen 2.10.8.1-1ubuntu2 (amd64 binary) in ubuntu quantal

 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 CLR (Common Language Runtime) including compiler and
 runtime, which can produce and execute CIL (Common Intermediate Language)
 bytecode (aka assemblies), and a class library.
 .
 This package contains the Virtual Machine, JIT (Just-in-Time) and
 AOT (Ahead-of-Time) code generator "mono-sgen".
 mono-sgen executes applications for the CLI (Common Language Infrastructure).
 Mono currently only supports the X86, PowerPC, ARM, SPARC, S/390, AMD64 and
 IA64 architectures.
 .
 This package uses SGen which is Mono's new simple generational garbage
 collector instead of Boehm's conservative garbage collector. SGen is
 currently only for testing and thus should not be used in production.
