Shinichiro Nakamura / NaturalTinyShell

Natural Tiny Shell (NT-Shell) library is a tiny shell library for a small embedded system. The interface is really simple. You should only know ntshell_execute in ntshell.h. So you can port it to any embedded system easily. Please enjoy your small embedded system with it. :)
