Help With Functions?

It looks like I'm going to need to use functions to get my tags to look like I want them too. Is there a guide that details what the commands do?

For example I am going to need to map track details to custom tags. I need help with this. I also want to list "featured" artists (from the track title) as additional artists in the track which means I need to use the commands to strip "Feat" or "Featuring" from the track title, identify the artist names, map them to the ARTIST tag and separate them with a \\.

How do I get started with this? I need expert advice for sure.

Thanks for the help.


The scripting functions are explained in the Help, Scripting page.
