17/**
18 * This is a host-side tool for validating a given edify script file.
19 *
20 * We used to have edify test cases here, which have been moved to
21 * tests/component/edify_test.cpp.
22 *
23 * Caveat: It doesn't recognize functions defined through updater, which
24 * makes the tool less useful. We should either extend the tool or remove it.
