6functions that might otherwise be vulnerable to hacking. This
7currently includes a standard suite of validation routines to be sure
8that an string argument acually converts to its intended type and a
9suite of string handling routine that do their own memory management
10in order to resist overflow attacks. In addition, a few functions are
11provided to standardize version and error reporting accross the entire
12suite of plugins. */
