    The default Mac OSX automounter is not replaced by this installation. Read
    http://fernandoff.posterous.com/ntfs-write-support-on-osx-lion-with-ntfs-3g-f
    for more infomation on how to replace the default automounter.

    Remember to install the fuse4x kernel extension as the root user.
    Instructions are found here: $(brew info fuse4x-kext).
