I don't like this :)

This is very dangerous. It will replace any tt. with at., regardless of where in the line, tt is found. It should somehow have a lookbehind that checks if tt was not preceded by a letter, underscore or a dot. From the little I know of sed, I think that it doesn't support look around conditions (see here)

@ricardoV94 just curious, do you not like this because its a bash script, or dont like the idea of an autoconverter?
