This FUSE-daemon allows to mount any DB as a simple filesystem. Unlike other similar "sqlfs" filesystem, it doesn't provide simple DB-backed file storage, but given you full interface to all database internals.
Every table, view, function etc. is a directory, every single field, index, record etc. is a file, symlink or subdirectory in the mounted filesystem. You can create table "mkdir ./mnt/tables/tablename", and remove them with "rmdir" afterwards. You can edit fields as simple YAML-files. All your usual file utilities are at your service including "find", "rm", "ln", "mv", "cp" etc.
Just mount your DB and enjoy!
