+# SFA Certificate Signing and management. Root authorities can use this script
+# to sign the certificate of another authority and become its parent. Sub
+# authorities (authorities that have had their cert signed by another authority)
+# can use this script to update their registry hierarchy with the new cert
+#
+# Example usage:
+#
+## sign a peer cert
+# sfa-ca.py --sign PEER_CERT_FILENAME -o OUTPUT_FILENAME
+#
+## import a cert and update the registry hierarchy
+# sfa-ca.py --import CERT_FILENAME
+#
+## display a cert
+# sfa-ca.py --display CERT_FILENAME
