google-drive-ocamlfuse is a FUSE-based file system backed by Google Drive,
written in OCaml. It lets you mount your Google Drive on Linux.

On the first time, just run google-drive-ocamlfuse, which will open a
browser for authentication. If that process succeeds, it will print
"Access token retrieved correctly.". Now run google-drive-ocamlfuse
with an empty directory supplied, which is the mount point for your Google
Drive. You can optionally unmount with fusermount -u mount-point.
