        Description: Filesystem in Userspace (FUSE) v3 library
         FUSE (Filesystem in Userspace) is a simple interface for userspace
         programs to export a virtual filesystem to the Linux kernel. FUSE
         also aims to provide a secure method for non privileged users to
         create and mount their own filesystem implementations.
         .
         This package contains the FUSE v3 shared library.
