Actually this page only contents my patched version of qmail-scanner. I don't know if it will content other stuff in the future.
I wrote the patch for my personal use, just modifiying the file qmail-scanner-queue.pl, and I shared it with some friends, then I started to modify the configure script and wrote a little documentation to install it. It was very interesting to study how Jason has done the configure script and add to it my options.
