How can you modify the default script templates when creating a new script file on Mac

How can you modify the default script templates when creating a new script file (C# / JavaScript) on Mac?

I found a potential solution in this thread:

http://answers.unity3d.com/questions/3726/changing-c-template

but this doesn't appear to apply to mac (at least I couldn't find the specified files).

It's in /Applications/Unity/Unity.app/Contents/Resources/NewBehaviourScript.cs , or wherever you installed it

You'll need to open the app itself to find it

As of Unity 3.4, they are now located here (Mac):

/Applications/Unity/Unity.app/Contents/Resources/ScriptTemplates/
