It successfully implements most of the functionality outlined in the statement of work, providing CruiseControl.NET integration, FogBugz/Manuscript integration, automated release note generation, and publishing workflows to cloud storage and help center platforms. + +## Solution Architecture + +The solution consists of 6 main projects in a modular architecture: + +### Project Structure + +```mermaid +graph TB + subgraph "Legacy Solution Structure" + MAIN[CCNetLogReader
