Noise modifier 1.0.0 for Maya (maya script)

I'm new to scripting (so I might be doing something wrong), but it took some effort to get this to actually work. The script doesn't work as-is because it's in RTF format. If you copy the text from the RTF file into a plain text file, rename it to *.mel, and delete the excess characters it works just fine. I'm using an older version of Maya, so this might not be an issue with newer versions at all.

Here's the working script, which you can copy directly:
