Mutter is a small Python library that runs a specified command when certain conditions are met. By default it will play sounds based on the return value of the provided command.
I intend to make it easy to write custom notifiers and smart resonders. Think growl notifications or intelligently only running a subset of a test suite.
An example invokation might be:
`mutter -c nosetests`
which would run nosetests whenever a file under the current path is changed, removed or added.
See `mutter --help` for more information.
