However, if you don't know what you're looking at, this may not help you much. If necessary, you can decompile compiled scripts to read them.
psc (and can be opened with notepad++ or similar). Not only that, but it can be very difficult to understand how scripts interact, even more so if they don't include the source code. in fact the CK wiki tutorial walks you through making a shitty script!). (And it's very very easy for a newb mod author to make a script that sucks. And scripts that suck can very easily damage your game because of how fragile papyrus is. That said, just like some mod authors make crappy plugins or textures that totally suck. No mod will compare to the vanilla script load. The single esp that loads the most number of scripts into the game is Skyrim.esm.
This is why some mods require SKSE - they need to do things that papyrus can't do. SKSE and Script Dragon both use injectors that can expand the number of things Papyrus can do. Papyrus is a bloody terrible engine and it has the bare minimum number of functions to do what the Bethesda devs needed to do. Scripts are pieces of code that can be interpreted by Skyrim's scripting engine, Papyrus.
