 The main executable of GSSAPI Console is `gssapi-console.py`.  The basic
 invocation works just like launching `python` -- use `gssapi-console.py FILE`
 to run a file in the established environment, or just run `gssapi-console.py`
 or `gssapi-console.py -i` to get an interactive environment (the `-i` flag
 can be used with a file, just like `python FILE -i`).
 
-You can use `--realm-args key1=true,key2=false,...` to pass specific arguments
-to the realm constructor (the set of such keys is driver-dependent), and
-`--mech MECH_NAME` can be used to specify a different driver (currently
-only `--mech krb5` will work).
+There are several additional flags that may be passed to `gssapi-console.py`:
+
+* `--realm-args key1=true,key2=false,...` can be used to pass specific arguments
+  to the realm constructor (the set of such keys is driver-dependent)
+* `--mech MECH_NAME` can be used to specify a different driver (currently, only
+  `--mech krb5` will work)
+* `-a IDENTIFIER, --attach IDENTIFIER` may be used to "attach" a new GSSAPI Console
+  session to an environment set up by an existing GSSAPI Console session.  The identifier
+  will be noted at the top of the existing GSSAPI Console session as `Session: IDENTIFIER`.
+* `-v, --verbose` may be used to increase the verbosity of the logging level (generally to
+  gain more details on what the driver is doing to set up the realm).
+
+Additional GSSAPI Console drivers may be introduced using the `gssapi_console.drivers`
+setuptools entry point.  They should follow the `gssapi_console.drivers.GSSAPIConsoleDriver`
+class.
+
+GSSAPI Console provides a [YALPT](https://pypi.python.org/pypi/yalpt) environment driver for
+writing tutorials and literate python files involving GSSAPI.  You can use it by passing
+`-e gssapi` to YALPT (it will use the default GSSAPI Console driver in this case).
