+You can create a simple echo client by running the "llecho.sh" to
+run the tests locally (over TCP loopback), or edit llecho.sh to
+specify the SERVER and CLIENT names. You would then set up as normal:
+
+ # if you are using a remote server, first run:
+ server# ../utils/lconf echo.xml
+
+Configure the client (or if you are running a single system only):
+
+ client# ../utils/lconf echo.xml
+ client# sh runregression-net.sh
+
+3. runtests
+
+The runtests script does a series of simple file-based tests using a
+filesystem. You need to have an XML file as appropriate for your setup
+(one or more hosts, including an MDS, one or more OSTs, and a mountpoint).
+If the MDS and/or OST is on a remote machine, configure them first:
+
+ ../utils/lconf --reformat <conf>.xml
+
+On the client machine, the runtests script needs the XML configuration
+file as a command-line parameter, as it mounts and unmounts the filesystem
+several times during the test in order to verify that the data is still
+there as expected (ensures that it makes it to disk instead of just into
+the filesystem cache). If you are running on only a single machine, you
+can just use runtests directly. If this is only a client machine, the
+--reformat parameter is not needed (it will not do anything).
+
+ sh runtests [--reformat] <conf>.xml
+
+This creates a few simple files and directories first, and then untars
+a copy of the /etc filesystem into the Lustre filesystem. It then does
+data verification both before and after the filesystem is remounted, and
+finally deletes all of the files and verifies that the amount of space
+left in the filesystem is (nearly) the same as it was before the test.
