## Advanced usage (multiple SSH sessions from a sub-shell)
This feature allows using regular SSH-related commands within a subprocess running user's shell.
`SSH_AUTH_SOCK` environment variable is defined for the subprocess (pointing to the SSH agent, running as a parent process).
This way the user can use SSH-related commands (e.g. `ssh`, `ssh-add`, `sshfs`, `git`, `hg`), while authenticating via the hardware device.
