Thanks, I updated my readme to include download links for the perl and python packages.
I'm pretty sure that nasm.exe and nasmw.exe now come with VS2012, at least the Ultimate version.
I really don't remember downloading them but don't have a fresh install to check. I could be wrong

However, I also use VS2010 and that didn't come with any nasm exe files which is why I used Netwide in the past.
Edit. I was wrong. I had an old version of nasm lying around. I will update my readme again. Thanks!
