+# $EPIC: longtoip.txt,v 1.2 2006/08/01 04:07:08 sthalik Exp $
+======Synopsis:======
+$longtoip(<integer>)
+======Technical:======
+   * If the <integer> value is omitted the empty string is returned.
+   * The <integer> value is taken to be a 32 bit unsigned integer.
+   * The <integer> value is taken to be in NETWORK ORDER.
+   * The return value is the dotted-quad IP address of <integer>
+======Practical:======
+This function does the reverse of $[[iptolong]]().  The DCC handshake uses
+'long's to swap ip addresses.  You can use this function to convert the 'long'
+into a dotted-quad IP address which can then be converted into a hostname by
+the $[[convert]]() function.  This can be used to look up the hostname of
+someone offering you a DCC connection.
+======Returns:======
+The dotted-quad IP address equivalent of <integer>
+======Examples:======
+<file>
+$longtoip(2131231747)                                returns "127.8.4.3"
+$longtoip(${(127 << 24) + (8 << 16) + (4 << 8) + 3}) returns "127.8.4.3"
+</file>
