naga v1.0

Naga is a terminal implementation of snake game. URL: http://github.com/anayjoshi/naga.
This is a first time addition of this project in homebrew. The project has existed for quite some time, the github repository was refurnished today.
Hmm, brew audit says `"* use "scons *args" instead of "system 'scons', *args"`.
I am a bit confused here. Isn't `system` necessary to run the command `scons` ? All documentation on homebrew that I came across definitely use `system` in the `install` function in the formula. Help would be appreciated!
