### BigSchema

This library is meant as a simple way to generate the big query boilerplate   
given a simple yaml based schema.


#### CLI Tool

The library comes with a simple command line tool that takes a source file,    
an optional destination directory default is ```./schema/``` and an output    
format and transforms the given yaml specifications to BigQuery compliant    
schema in the desired output format.

```bash
$ bigschema --help
