There is also a perl script called logresolvemerge.pl that is part of 
the awstats program that may work - although I'm not sure if either of 
these will adjust out-of-order source files.  They are intended to merge 
  already sorted files into one for analyzers that aren't bright enough 
to do it themselves.  Analog complains about possible duplication but 
doesn't seem to choke if you just give it a big list of files.
