# This directory is an example of how to build extensions to the spec.
# Typically this would be in a top-level extensions/ directory.
#
# In this example we build an extension for the TpConnection class,
# by using "--subclass=TpConnection --subclass-assert=TP_IS_CONNECTION".
# We could instead (or additionally) have made an extension for any other
# class, or by omitting those options entirely we could have made an extension
# that will work on TpProxy or any subclass of TpProxy.
