I've used the wrap-program as an alternative to the your suggested solution.

Going through the program there is a function update_fwdb [1] that downloads and updates database files when the script is executed with the --update-fwdb argument.

I've added both files [2][3] in question to the lists of inputs.

However, since they are supposed to be updated at runtime (stored in $HOME) I don't know to represent this in the package definition.

Could you please suggest how to proceed?
