Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
routing: Add new roundup.web namespace with router component This branch is to untangle hardcoded Roundup URL scheme, make it more readable and customizable with extensions. Right now it doesn't seem possible to write extension that renders static HTML page at /about without modifying Roundup DB, and this web component should not depend on DB schema.
