/*
 * Test suite for kafs library.
 *
 * This is the backend program run by the kafs-t driver script.  It first
 * checks whether k_hasafs returns true.  If it doesn't, it exits with status
 * 2, indicating that all tests should be skipped.  Otherwise, it runs
 * k_setpag, then tokens, then aklog, then tokens, and then k_unlog, sending
 * the output to standard output and errors to standard error.  If either
 * k_setpag or k_unlog return failure, it reports an error to standard error
 * and exits with status 1.  If aklog or tokens fails, it exits with status 3.
 * If the commands all finish, it exits 0.
 *
 * The canonical version of this file is maintained in the rra-c-util package,
 * which can be found at <https://www.eyrie.org/~eagle/software/rra-c-util/>.
