+Version 1.13.1 (RGer), 2007-02-xx
+- changed the listen backlog limit to a more reasonable value based on
+ the maximum number of TCP connections configurd (10% + 5) - thanks to Guy
+ Standen for the hint (actually, the limit was 5 and that was a
+ left-over from early testing).
+---------------------------------------------------------------------------
Version 1.13.0 (RGer), 2006-12-19
- added '$' as ToPos proptery replacer specifier - means "up to the
end of the string"
