+Module: mod_nvram
+Author: Brian Wotring (brian@shmoo.com)
+
+
+
+DESCRIPTION:
+
+The mod_nvram module reads the key=value pairs stored in nvram.  This
+is primarily for Linksys routers, but could be modified to run on
+other systems if necessary.  On the routers like the WRT54G, the 
+nvram settings hold sensitive information that needs to be monitored.
+The format for the record structure is as follows:
+
+    name:value
+
+USE:
+
+To use this module, all  that is needed is to include it in the System
+block of a scan configuration, e.g.:
+
+    <System>
+    ...
+    Include mod_nvram
+    ...
+    </System>
+
+
+PARAMETERS:
+
+There are no parameters for this module.
+
+PLATFORMS:
+
+Currently, only for the Linksys WRT54G and WRT54GS devices.
