While this may be pedantic, I'm curious about the proper usage, if any.
We have a piece of software that opens a file, increments a counter in the file, and closes the file. This piece of software is called Incrementor, but it looks funny to me. I think it should be called Incrementer, as it is one who or thing that performs an increment.
I am a software developer (one who or thing that develops software), not a software developor.
I pay rent, I am a renter, not a rentor.
I increment numbers, therefore I am an incrementer, not an incrementor.
Any thoughts or rules that can help out?
