 +======Synopsis:======
 +$__numwords__(<word list>)
 +
 +======Technical:======
 +This function serves as a replacement for the $#var notation when you
 +want to count the words in a string not held in a variable.
 +
 +======Practical:======
 +This function is used to count the number of words in an arbitrary
 +string.  Normally, you could get this value with the $#var form, but
 +that doesn't work for parameter expandos or function return values.
 +
 +======Returns:======
 +number of words in given string
 +
 +======Examples:======
 +<file>
 +$numwords(hello there bob)                returns 3
 +$numwords()                               returns 0
 +</file>
