automating wwwoffle-write

Howdy,

the situation is as follows.  I have a file url.txt with lines

  http://host1/a.pdf
  ftp://host2/b.exe

a.pdf and b.exe are big files so I use "wget -ci url.txt" for them. 
After download I want to import the files into the WWWOFFLE cache.  Of 
course, I can do this manually with wwwoffle-write, but I was wondering 
if anyone on this list has written a script to automate the process.  If 
not, can anyone see a flaw in the following algorithm?

  1) for each file in the dl dir do a grep on url.txt to find the line
     with url. If no match go to 4).
  2) cat $file | wwwoffle-write --add-header $url
  3) rm $file
     (unprocessed files are left in the dir and can be dealt with)
  4) ouput name of $file and report on success or failure
  5) go to next file

Of course, this won't deal properly with index.php?fileid=abc where the 
resulting file is def.pdf.  But will this do for "normal" situations or 
at least not break things too easily?

Best

Rolf
