 * This file provides functions very similar to "sprintf()", but which
 * not only parse some additional "format sequences", but also enforce
 * bounds checking, and allow repeated "appends" to the same buffer.
 *
 * See "z-form.c" for more detailed information about the routines,
 * including a list of the legal "format sequences".
 *
 * This file makes use of both "z-util.c" and "z-virt.c"
