As do I.

However as with any code I published I would be fairly annoyed were someone to lift it and present it as their own without either first contacting me (which is trivial) or citing me.

I have found a lot of references to things I have done on google scholar et al and I am flattered to have been included.

I don’t understand why anyone would risk being caught out like this. Citing is trivial and indicates you have done research and then built on someone else’s work.
