# Utility to clean build machine

# DISABLED will prevent builds of that build type to not be cleaned up.
# This is needed such as during the 2 or 3 weeks that we have a release
# candidate, but do not publically make visible until the Simultaneious
# Release. In those cases, we want to keep the originally named build around,
# as well as any renamed versions of it. Valid values are the standard one
# character "build types" we use (I,M,N,P). Leave blank (or commented out)
# if nothing should be disabled.
