a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

var styles = r.style.cssText.split(/;(?![A-Za-z0-9])/);
for(var i = 0; i < styles.length; i++) {
if(!!styles[i] === false) continue;
var pair = styles[i].split(": ");
