Untraceable digital cash in D

[FellowTraveler]

Greetings, D aficionados.

I only regret that I did not discover your wonderful language sooner, as I probably would have written my entire library in D instead of using C++.

In the meantime, since I was already using SWIG, I have added bindings for the D language, so you can add untraceable digital cash, and other cool financial cryptography, to your D projects:
