We need to have a copyright notice in all code files. We want this to happen transparent to the user by setting up a precondition that executes upon delivery.

Basically the Code Delivery Precondition needs to apply the following logic (without prompt or any change to the UI):

1. Check if file type is code, based on extension.
2. If yes, check file for existing copyright text.
3. If copyright text exists and year is old, update to current year.
4. If copyright text doesn't exist, add it.
5. If changed, re-save the file.
6. Continue the delivery.

I know how to setup a precondition. What I don't know is how to write or install the extension that does the logic listed above. I assume we need to use the Java API and write this in Java, but I really don't know. I have a Java programmer on hand if needed, but I need to tell them what hooks to use and how to use them. How do I accomplish this? Please don't send me to large generic lists of instructions for extending RTC - I can't follow them without knowing what I can ignore based on the logic listed above. This does not involve any prompts or changes to the UI and instructions I found did not take that into account.

I have seen similar questions asked and I added to other threads but have not gotten an answer, so I am trying my own thread. :)
