Long story short, how exactly do you install Avisynth filters and plugins? I've managed okay with simple things like single .dll files, that's easy enough, just download it to the plugin directory... but now I'm running into big zip archives of dozens of files and I have no idea where they're supposed to go. I've been reading readmes and Googling like a madwoman, but even the Avisynth wiki is silent on exactly how these things are to be installed. I feel like a total idiot having to ask this, but all I'm getting on my own is frustrated.

For example, at the moment I'm trying to use vmToon. I got the vmToon .avs file, renamed it to .avsi, and put it in the Plugins directory... but I was also missing MaskTools, which is where I'm running into the problem. There are a ton of files for it on http://manao4.free.fr/ and I'm not sure exactly what I need. I saved the masktools dlls to my plugins directory but I got "there is no function named mt_lutxy" when I tried to use vmToon. I downloaded the archive masktools-v2.0a29.zip which seemed to be the newest version, but I'm not sure what I'm supposed to do with it. I tried unzipping it to the plugin directory, etc, but I keep getting that "no mt_lutxy" error. Am I putting it in the wrong place? There are tons of instructions for using MaskTools around, but nothing on how you actually install the thing!
Sorry for the long post, I've been struggling with this for a couple of hours now and it's driving me crazy. Have pity on this ignorant n00b ;_;
