TortoiseSVN + Trac Integration

TortoiseSVN supports integration with various issue tracking systems via some properties added to the top-level checkout. This integration adds a separate column for ticket numbers and activates clickable links to tickets in the TSVN log dialog.

See: ​http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-bugtracker.html

For integration with Trac, the following properties work well:

bugtraq:url	http://trac.edgewall.org/ticket/%BUGID%
bugtraq:logregex	(?:ticket: *|#)(\d+) *(?:, *(\d+))*
bugtraq:label	Ticket

You should change the url property to the url for your Trac installation. The label property is optional, and just changes the text label for issue numbers.
