Summary: divide by zero error while building

Initial Comment:
Hello, 
 
Today i found a small problem with InstallBase: you 
get a divide by zero error if you want to add a file 
with length zero.  The error is: 
Packing nameofmyemptylogfile... 
divide by zero 
  while executing  
"expr round($conf(wrapSoFar) * 100.0) / $size )" 
  (procedure "::MPI::WrapProgress" line 8) 
  invoked from within 
"::MPI::WrapProgress $totalSize $size $size" 
  (procedure "::MPI::wrap" line 158) 
  invoked from within 
"::MPI::wrap -verbose -x {C:/Program 
Files/InstallBase/Installs/Install 
eDocPort/eDocPort/eDocPort-Setup.exe} -wintcl 
{C:/Program Files/InstallBase/Binaries/Win...' 
("eval" body line 1) 
invoked from within 
"eval::MPI::wrap -verbose $argv " 
 
 
It's not really a problem for me, the logfile is also 
created if it doesn't exist yet. But it might be 
interesting for you to know that it doens't yet 
handle empty files correctly. Thanks for creating 
such a great program! 
 
Kind regards, 
Dries Verachtert
