+# Simply util to grep through network definitions.
+# Examples:
+# To find out which tokens contain "10.4.3.1" use
+# $ cgrep.py -i 10.4.3.1
+#
+# To find out if token 'FOO' includes ip "1.2.3.4" use
+# $ cgrep.py -t FOO -i 1.2.3.4
+#
+# To find the difference and union of tokens 'FOO' and 'BAR' use
+# $ cgrep.py -c FOO BAR
