annotate website/issues/extensions/spambayes.py @ 7478:e8d2a4bca16a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Update index. Add "track your issues your way" tag line and... Add description of benefits to some of the noteworthy changes. Add GTD "thing management" from old email in the 1.6 time period. Reverse order of fast gratification so source directory is first then venv install. Match the first line that says you don't have to install.
