+- `/opt/socket_vmnet/bin/socket_vmnet`
+- `/opt/socket_vmnet/bin/socket_vmnet_client`
+
+You can customize the install location using the `PREFIX` environment variable,

+only written by the root. Note that `/usr/local/bin` is sometimes chowned for a
+non-admin user, so `/usr/local` is _not_ an appropriate prefix.
