+define Package/spoofer/description
+The spoofer client is part of a system to measure the Internet's
+resistance to packets with a spoofed (forged) source IP address.
+
+This package comes bundled with a small certificate file that allows
+secure communication with the spoofer server without depending on
+the large ca-certificates package.  But if the server's private
+certificate ever changes, it will be necessary to either install the
+ca-certificates package or install an updated version of this package
+that has a newer bundled certificate.
