Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
First step of removing the cache blob. The static part of the describe document will be created by using the input data stored at each state. Some TODOs left (see ChangeLog). gnv-artifacts/trunk@671 c6561f87-3c4e-4783-a992-168aeb5c3f6f
