this program list FUSE directory bindings.
FUSE binds are useful for restict permissions or change uid/gid of files on a directory.
for example Android use FUSE for show ext4 partitions as FAT ( like /data/media on /sdcard ).
retrieve source directories for these bindings allow you to access to the real filesystem, thus to have full control over file modes and symlinks.
i wrote that for hacking Android permission restrictions, but you can use it everywhere.
report bugs to the github issue page.
