# default make action is "all" - build all packages
#
# We build all l4env headers (idl+includes), then all l4env libs, then the
# l4env servers and examples. Then we build the other headers
# (idl+includes), the other libs, the other servers and examples. We use
# dependencies for this, witch might allow parallel build processes.
