{{alias}}( path, clbk )
    Asynchronously tests whether a path exists on the filesystem.

    Parameters
    ----------
    path: string|Buffer
        Path to test.

    clbk: Function
        Callback to invoke after testing for path existence. A callback may
        accept a single argument, a boolean indicating whether a path exists, or
        two arguments, an error argument and a boolean, matching the error-first
        callback convention used in most asynchronous Node.js APIs.

    Examples
    --------
    > function done( error, bool ) { console.log( bool ); };
    > {{alias}}( './beep/boop', done );


{{alias}}.sync( path )
    Synchronously tests whether a path exists on the filesystem.

    Parameters
    ----------
    path: string|Buffer
        Path to test.

    Returns
    -------
    bool: boolean
        Boolean indicating whether the path exists.

    Examples
    --------
    > var bool = {{alias}}.sync( './beep/boop' )
    <boolean>
