// Ok we want a lot of different parts of the DNS API in the python
// module, but not one big 10000-line file.
// So we split it up in several 'mini-modules'
// These would be the same as a single module, except for
// the init function, which has to be modified to a unique
// name initModulePart_<name>, and return true/false instead of
// NULL/*mod
//
// And of course care has to be taken that all identifiers be unique
