mono-runtime 2.4.3+dfsg-1ubuntu2 (i386 binary) in ubuntu lucid

 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".
 "mono" executes applications for the CLI (Common Language Infrastructure).
 Mono currently only supports the X86, PowerPC, ARM, SPARC, S/390, AMD64 and
 IA64 architectures. Optionally this package configures BINFMT support.
