UpstreamImporter - needs work (Constantly polls openjdk repos in order to pull in changes, into the Betterrev server.)
MercurialImporter does some stuff already, needs more work (Pulls in code from a mercurial repository, keeping an internal hg repository up to date.) - has MercurialImporterTest as well. @Richard Warburton thinks this one is pulling code from the adoptopenjdk sub-repos under Adopt OpenJDK org into the Betterrev server.
./scripts/hgforest.sh - push changes from local machine to adoptopenjdk organisation as user adoptopenjdk / otheruser
We need to write a wrapper (akka-fy) around hgforest.sh to be able to call it from the server to push code into the Adopt Openjdk sub-repos in the Adoptopenjdk organisation in Bitbucket.
