+This module (relpipe-lib-protocol.cpp) is deprecated and no longer used since v0.15.
+It was fully replaced by the relpipe-lib-common.cpp module (a renamed fork of this module).
+This mercurial repository remains available just to make it possible to build v0.14 and older versions of Relational pipes.
