There is no explanation about how one should fill in the $convmap parameter. 
There is only a very cryptic example.

A thorough explanation should be given of how many elements the array should 
contain and what exactly is the meaning of each ones. It is not obvious at all 
and pretty hard to figure out from the given example.

Maybe it is explained somewhere else in the docs in another function's reference. 
If so a link or pointer should be given.
