undefined reference to main

[blippy]

In a directory called blinkr I have blinkr.nim and config.nims, which are as per the front page of the ratel repo.

I type ratel build, and get the response:

Hint: used config file '/home/pi/.choosenim/toolchains/nim-1.6.6/config/nim.cfg' [Conf]
Hint: used config file '/home/pi/.choosenim/toolchains/nim-1.6.6/config/config.nims' [Conf]

Ah yes, I made a tiny change in the repo so you need to update to 0.2.1. Just run nimble install ratel again
