+# List the protocols (dissectors) used in capture file(s)
+#
+# The Python script indexcap.py does the same thing.
+#
+# This script extracts the protocol names contained in a given capture file.
+# This is useful for generating a "database" (flat file :-)) of in what file
+# a given protocol can be found.
+#
+# Output consists of the file name followed by the protocols, for example:
