- v2.2.0 June 24, 2013
	- Split from [bal-util](https://github.com/balupton/bal-util)
	- `spawn` is now safe rather than just `spawnCommand`
	- `spawn` now waits for `close` instead of `exit`
		- Thanks to Johny Jose for
[balupton/bal-util#9](https://github.com/balupton/bal-util/pull/9)
	- `getEnvironmentPaths` now uses `require('path').delimiter` for
seperation
	- `getStandardExecPaths` now uses `require('path').join` for joining
`execName` to a possible path
	- `initGitRepo`, `initOrPullGitRepo` and `initNodeModules` now use
`opts.cwd` instead of `opts.path`
