annotate roundup/cgi/cgitb.py @ 5695:3e1b66c4e1e2

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Update docs. Correct errors reported by setup.py build_docs. Add rest interface and link to rest doc to features page. Add link to xmlrpc doc to features page. Add rest doc to index. Update rest doc, hopefully clarify confusing use of parameters in patch action section. Fix code examples in "Adding new rest endpoints" section. Fix example adding import of exception.
