Hey David,

This looks like an interesting little project,
however I'm unsure on copyright matters etc etc.

I read the source code in:
https://github.com/D-Programming-Language/dmd/blob/master/src/root/response.c

Could you explain what needs to be done exactly ?
e.g.:
   How should such a clean room implementation look like ??
   Does the structure need to change ??
   Is it enough to rewrite the code in D ??
   Should the code be in C if so how much change ??

Well just some thoughts, but the code looks pretty straight 
forward..

Gr,
Danny Arends
