# This make file create the echttp library, plus a handful of tool, mostly
# for testing purposes.
#
# The echttp library can be built as a shared object (it works), but sharing
# creates a deployement codependency. This could be managed through versioning,
# but that requires more work than it is worth.
#
# The shared object building rules were kept here, nonetheless, as they
# might become useful in different deployement contexts (containers?).
