/*
 * PAM interaction script API.
 *
 * Provides an interface that loads a PAM interaction script from a file and
 * runs through that script, calling the internal PAM module functions and
 * checking their results.  This allows automation of PAM testing through
 * external data files instead of coding everything in C.
 *
 * 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/>.
