Other ways to flag an AUT registry change(s)?

Hello,

I created the following python scripts (Python 3.2) and would like to incorporate them into TC (v12.42).

- Script 1:  Extract specific HKCU registry settings and pipe the results to a txt file

- Script 2:  Compare and identify differences between two txt files 

The goal is to quickly check differences in the registry key and/or values for in-development builds (i.e., build 52, 53, etc).  For the most part, there should be zero to minimal registry changes.  We want to quickly spot unknown/unplanned changes, especially at the latter part of the development cycle. 

Other than incorporating TC's Log.Message(name, value, type) command into the python scripts to send a message to "Additional Info", any suggestions/recommendations to flag TC of any registry change(s)?

Thank you

john
