description         A FUSE-Compliant File System Implementation Mechanism for Mac OS X
long_description    MacFUSE implements a mechanism that makes it possible to implement \
                    a fully functional file system in a user-space program on Mac OS X \
                    (10.4 and above). 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. The core of MacFUSE is in a dynamically loadable kernel extension.
