# Several targets in this Makefile expect to run within the
# libnetworkbuild container.   In general, a target named '<target>-local'
# relies on utilities inside the build container.   Usually there is also
# a wrapper called '<target>' which starts a container and runs
# 'make <target>-local' inside it.
