 +======Synopsis:======
 +$__iptoname__(<ip address>) \\
 +$__nametoip__(<hostname>)
 +
 +======Technical:======
 +These functions are used to convert an IP address to a hostname, and vice
 +versa.   The $__iptoname__() function returns the hostname associated with
 +the given IP address, and $__nametoip__() does the opposite.
 +
 +======Practical:======
 +These functions are used to convert between IP addresses and Internet
 +hostnames.  Obvious reasons aside, they are mostly useful when you know
 +which of the two the input will be.  They return nothing if the address
 +could not be converted, or if the input was invalid.  The $[[convert]]()
 +function should be used if the input is known to vary.
 +
 +======Returns:======
 +iptoname: hostname for the given IP address \\
 +nametoip: IP address for the given hostname
 +
 +======Examples:======
 +<file>
 +$iptoname(127.0.0.1)         probably returns "localhost"
 +$nametoip(localhost)         probably returns "127.0.0.1"
 +$iptoname(localhost)         error, input is not an IP address
 +$nametoip(127.0.0.1)         error, input is not a hostname
 +</file>
