It's as I posted here. Tango may use any part of Phobos and *relicense* 
it under the Tango license that I have the power to do.

I don't know what more needs to be elaborated. There are two reasons for 
this:

1. To ensure Phobos is free of any legal taint and any accusations of 
stealing code.

2. To avoid the untenable issue of a single module in Phobos having 
different license for different lines of code.

What specifically I'd like from the Tango team is explicit permission 
for the Phobos team to go over the Tango code and be able to copy/use 
whatever portions of it are necessary to get the two libraries to have a 
compatible core, and to relicense those parts under the corresponding 
Phobos license.

I have already provided a reciprocal agreement for the Tango team to use 
Phobos.
