Add make-manuf, a script that:

  - Reads our current 'manuf' file header and contents

  - Fetches OUI information from the IEEE and CaveBear

  - Merges the OUI information, with our entries taking precedence, then
    CaveBear's, then the IEEE.

  - Dumps eveything into the 'manuf' file.

+# Make-manuf - Creates a file containing ethernet OUIs and their
+# company IDs.  It merges the databases at
+# http://standards.ieee.org/regauth/oui/index.shtml and
+# http://www.cavebear.com/CaveBear/Ethernet/
+# with entries in our template file.
+#
+# The script reads the comments at the top of "manuf.tmpl" and writes
+# them to "manuf".  It then joins the manufacturer listing in "manuf.tmpl"
+# with the listing in "oui.txt", with the entries in "manuf.tmpl" taking
+# precedence.
