To install from source, first checkout this project and then navigate your
command-line interface to the outer hairball directory that contains ``. Then run `python install`.

## Running Hairball

Once installed, to see how to use hairball run `hairball --help`. That will produce output similar to the following:

scratch files. Multiple PATH arguments can be provided.

--version show program's version number and exit

Plugins in this directory take precedence over
similarly named plugins included with Hairball.

Use the named plugin to perform analysis. This option
can be provided multiple times.
