+======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>
