15# Setting this to non-empty will remove the old content of the buildhistory as part of
16# the current bitbake invocation and replace it with information about what was built
17# during the build.
18#
19# This is meant to be used in continuous integration (CI) systems when invoking bitbake
20# for full world builds. The effect in that case is that information about packages
21# that no longer get build also gets removed from the buildhistory, which is not
22# the case otherwise.
23#
24# The advantage over manually cleaning the buildhistory outside of bitbake is that
25# the "version-going-backwards" check still works. When relying on that, be careful
26# about failed world builds: they will lead to incomplete information in the
27# buildhistory because information about packages that could not be built will
28# also get removed. A CI system should handle that by discarding the buildhistory
29# of failed builds.
