This will avoid unnecessary work and surely give you and us a good deal of inspiration. * Relevant coding style guidelines are the [Go Code Review Comments](https://code.google.com/p/go-wiki/wiki/CodeReviewComments) and the _Formatting and style_ section of Peter Bourgon's [Go: Best Practices for Production Environments](http://peter.bourgon.org/go-in-production/#formatting-and-style). prometheus_cli-0.3.0/LICENSE000066400000000000000000000261351250537117700155600ustar00rootroot00000000000000 Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
