The software "Dregg" (saxon vernacular for "Trac") is a small, quick and dirty hack to get ticket data from an instance of "Trac".
It queries a hardcoded trac instance for tickets to a given milestone that contain the string "#RN" in comments or changesets to be able to automate the release note generation.
After the query an ANSI CSV file is generated and opened with the default application.
It is not really generic but might be useful as a base to start with C#, Trac and the XMLRPC Plugin using JSON RPC as technology.
