Zeta
Zeta is a Command interpreter built purely in C for Windows OS. It provides a command- line interface to access common services for calculation and manipulation of data.
Zeta has been built at an 'implementation-scale'. Apart from the standard Windows OS command-line utility (CMD), Zeta can also be used.
Development has been discontinued as of Aug 2013 (Send a pull request if you want to contribute)
