I modified Miguel Ferreira Simoes XML library to use Mango instead of Phobos 
(except for std.string.letters and similar). Now, he released it with a BSD 
style license (I think). I want to make my changes public, but I don't know if
I 
can add another license (zlib) to the existing, or if I can replace it, how to 
keep copyrights, etc. Or should I just keep his license and just add my name to 
the "author" section, also update date, version, etc.?

I believe the terms of the BSD are basically: "do whatever you like,
just make sure you attribute the original source in both source and binary."

Looking at the zlib license, it's mostly the same except that it doesn't
have the second BSD clause:

"Redistributions in *binary form* must reproduce the above copyright
notice, this list of conditions and the following disclaimer in the
documentation and/or other materials provided with the distribution."

Nor does it have the non-endorsement clause.

So I don't think the zlib license would be compatible.  The safest thing
to do would just be to distribute the changed version under BSD as well.
 If you really *really* want to apply the zlib license, then consult a
lawyer.

No, I don't really *really* want to, it was just personal preference. Anyway, 
thanks for that, I'll keep the same license, then.
