# In theory 'export DH_GOLANG_GO_GENERATE:=1' should suffice, but for
# some reason it does not re-generate the files generated by code
# under _gen/.  So we need to do that part manually.
#
# The complexity below is mostly to confirm that the re-generated
# files are identical to the shipped sources.  Otherwise we could
# introduce a problem if we would use different re-generated source
# code files due to some tool reason (e.g., build dependency changes).
#
# Two files cannot be reproduced still, so we exclude them for now:
