-Test nodes can be in either kernel or userspace. A console user can
-invite a kernel test node to join the test session by running
-.I "lst add_group NID",
-but the user cannot actively add a userspace test node to the
-test-session. However, the console user can passively accept a test
-node to the test session while the test node runs lstclient to connect
-to the console.
-.SH UTILITIES
-LNET self-test has two user utilities, lst and lstclient.
