[Mono-dev] Mono on Embedded Platform

[techi eth]

Thanks for input.

I have strip the binaries.I nearly coming size mentioned above.

I still need to play with mkbundle.

Currently i have done manual picking of my required assemblies out of mono
build.Is their any way i can get this by enabling disabling configure
option or any other better way i can use.
