Foam Gods: Can results files be added together and scaled easily?

As they are text files I'm wondering if it's easier to bodge together something in python (after hunting all afternoon on the forums) ... but there has to be a better way?

Looked in postProcess, but "add" and "scale" aren't there. funkySetFields isn't installed so would need compiling...

(Using blueCore openfoam 4.x)

There is a postProcess function named add in OF5 and up.
Code:
postProcess -func "add(FIELD1, FIELD2)"
Alternatively, you can make use of the calculator filter in paraview, however the file format will differ from that used by openFoam.
