Easiest way to get one is to go to this link,
click on "Enable the Drive API" button, follow the steps and download the file.
Usage
Download the source, cd to the drivefs dir and build it go build drivefs.go
$ ./drivefs -credsfile <path to credentials.json> -mntpoint <path to mount dir> -tokenfile <path to oauth token.json>
On first run, it will print a link to authorize the app and fetch an oauth refresh token.
NOTE: Since the authorization is for your own app created in the pre-reqs step, it should be fine to proceed,
however, make sure the file is stored in a safe location on the machine after download.
It will fetch basic file/dir information (not the actual contents), and the mounted directory can be browsed using
a regular file manager/shell.
