description         A FUSE-Compliant File System Implementation Mechanism \
                    for Mac OS X
long_description    FUSE for OS X implements a mechanism that makes it \
                    possible to implement a fully functional file system \
                    in a user-space program on Mac OS X. It aims to be \
                    API-compliant with the FUSE (File-system in USErspace) \
                    mechanism that originated on Linux.  Therefore, many \
                    existing FUSE file systems become readily usable on \
                    Mac OS X. This port provides the user-space library \
                    and header files for building filesystems.

    When upgrading, unmount all FUSE filesystems and then unload the kernel extension.
    Unloading can be done via: sudo kextunload -b com.github.osxfuse.filesystems.osxfuse
    Alternatively (or if this fails), just reboot your computer now.
