# Manage indirections to termini.  They are organized in terms of indirections -
# - e.g., configuration, node, file, certificate -- and each indirection has one
# or more terminus types defined.  The indirection is configured via the
# +indirects+ method, which will be called by the class extending itself
# with this module.

  # to override it.
