Usage: $0 PROFILEID DIR
  PROFILEID The Sonatype profile to use for staging repository
            Obtain profile ID from https://oss.sonatype.org:
             * Build Promotion > Staging Profiles
             * Select profile based on name (e.g., 'io.grpc')
             * Copy hex identifier from URL after "#stagingProfiles;"
  DIR       Directory to upload to Sonatype as a new staging repository

~/.config/sonatype-upload: Configuration file for Sonatype username and password
  USERNAME=yourusername
  PASSWORD=yourpass

Sonatype provides a "user token" that is a randomly generated username/password.
It does allow access to your account, however. You can create one via:
 * Log in to https://oss.sonatype.org
 * Click your username at the top right and click to Profile
 * Change the drop-down from "Summary" to "User Token"
 * Click "Access User Token"
