Bitten supports the ability to link between any wiki-enabled objects in Trac.
To link to a particular build, use the TracLink syntax build:N
(where N is the number of the build).
Linking to a particular step of the build is also supported by adding an
anchor reference, like build:N#Test. If the step ID contains spaces,
the link must be quoted: build:"N#My Step".
