Setupstorage-dropbox is the second step in establishing an upspinserver.
It sets up Dropbox for your Upspin installation. You may skip this step
if you wish to store Upspin data on your server's local disk.
The first step is 'setupdomain' and the final step is 'setupserver'.
Setupstorage-dropbox creates the server configuration files in $where/$domain/ to use
the specified authorization code to access your Dropbox.
Before running this command, you must obtain an authorization code:
1. Go to
2. Click "Allow" (you might have to log in first).
3. Copy the authorization code
4. Run setupstorage-dropbox -domain <domain.tld> <authorization_code>
