Gofish is a fuse fs for mounting your Google drive.
gofish_fuse3 is the current version, gofish_netbsd is the last version based on the high level fuse interface.
This is built on libfuse3 and has (beta) support for writing.
Gofish was originaly developed on NetBSD, this version is in the gofish_netbsd folder. This will work against the netbsd fuse.h using puffs but still has some thread locking issues; so is prone to locking up occasionally. it is designed using a dual thread aproach with the Qt event loop being run in the main thread and the fuse event loop in a secondary fuse thread. It has issues and is unlikely to be updated.
