19 * This section overrides some definitions below for test purposes.
20 * When compiled with -DTEST_CMDGEN:
22 * - Calls to get_random_data() are replaced with the diagnostic
23 * function below (I #define the name so that I can still link
24 * with the original set of modules without symbol clash), in
25 * order to avoid depleting the test system's /dev/random
28 * - Calls to console_get_userpass_input() are replaced with the
29 * diagnostic function below, so that I can run tests in an
30 * automated manner and provide their interactive passphrase
33 * - main() is renamed to cmdgen_main(); at the bottom of the file
34 * I define another main() which calls the former repeatedly to
