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.

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