# This PortGroup adds dependencies and arguments for building with gobject
# introspection. There is just one option to set:
#
# gobject_introspection: whether to use gobject introspection. The default
# is no. Possible values are yes and no.
#
# It is imperative to either set this option *after* you set the port's
# dependencies, not before, or alternately, ensure you always append to
# dependencies rather than overwriting them. Otherwise you'll overwrite
# the dependencies the portgroup sets.
