-This command should return a cool quote like:
-<pre>
-"Whatever Happened to Pong ?" (F. Black)
-</pre>
+This command should print out information about the version of Gromacs
+installed.
If this, in contrast, returns the phrase
<pre>
-luck: command not found.
+mdrun: command not found.
</pre>
then you have to verify where your version of GROMACS is installed.
