   "This is a powerful array class providing PHP style arrays in TorqueScript.\n\n"

   "The following features are supported:<ul>\n"
   "<li>array pointers: this allows you to move forwards or backwards through "
   "the array as if it was a list, including jumping to the start or end.</li>\n"
   "<li>sorting: the array can be sorted in either alphabetic or numeric mode, "
   "on the key or the value, and in ascending or descending order</li>\n"
   "<li>add/remove elements: elements can be pushed/popped from the start or "
   "end of the array, or can be inserted/erased from anywhere in the middle</li>\n"
   "<li>removal of duplicates: remove duplicate keys or duplicate values</li>\n"
   "<li>searching: search the array and return the index of a particular key or "
   "value</li>\n"
   "<li>counting: count the number of instaces of a particular value or key in "
   "the array, as well as the total number of elements</li>\n"
   "<li>advanced features: array append, array crop and array duplicate</li>\n"
   "</ul>\n\n"
