Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add command logging. Set RECORD_COMMANDS=1 to log every command line run by the build into log files named "build/cmdlines.$STAGE.$PACKAGE".

55 # so it's nice to know as early as possible that we actually needed it.
56 #
57 # 2) Quick smoke test that the versions of the tools we're using can compile
58 # everything from source correctly, and thus mini-native should be able to
59 # rebuild from source using those same tools.
60 #

62 # same command line utilities no matter where we're running, because we
63 # provide our own.
