+<p>
+The command lists the RPMs installed inside a Fedora / RHEL / CentOS
+or other RPM-based virtual machine.  It does this by running the
+<code>rpm -qa</code> command directly inside the machine.
+</p>
+
+<p>
+To use it you need to know the partition or LV <i>inside</i> the
+VM that contains the root filesystem, so for example:
+</p>
+
+<pre>
+rpmqa.sh guest.img /dev/VolGroup00/LogVol00 | less
+</pre>
+
+<p>
+You can write a similar command for Debian-based virtual machines
+very easily.
