Enoch does not do those other things that Clover does, like all those ACPI patching. For kext patching, I believe it's self explanatory: it completes a find/replace action on cached kext just as Clover does. The code is expressed in Base64 as per Clover if you open up a Clover config in, say, TextEdit.
Again, all is explained in the IM thread I linked above.
