+# $PREFIX/iraf_extern/package_name, add any configuration files from the conda
+# recipe (eg. ur_extern.pkg) and update extern.pkg accordingly. This is
+# normally done *before* building the package in place, since it (and its
+# dependencies) already have to be defined in IRAF at build time and the source
+# gets distributed anyway.
