+#   [MS-SCMP]: Shadow Copy Management Protocol Interface implementation
+#              This was used as a way to test the DCOM runtime. Further 
+#              testing is needed to verify it is working as expected
+#
+#   Best way to learn how to use these calls is to grab the protocol standard
+#   so you understand what the call does, and then read the test case located
+#   at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC
+#
+#   Since DCOM is like an OO RPC, instead of helper functions you will see the 
+#   classes described in the standards developed. 
+#   There are test cases for them too.
