Different License: (altogether different)

std.recls:

The recent version of recls uses a BSD license instead,
http://www.opensource.org/licenses/bsd-license.php
and std.loader should probably just be replaced anyway...
So by updating recls, that should more or less go away ?

md5 and random might still be a problem, but can be fixed.
There is a RSA-free version of MD5 available at: (C code)
http://sourceforge.net/projects/libmd5-rfc/
(And Walter has already made qsort2.d, into Public Domain)


So I think most of the Phobos licensing issues are sorted out ?
(then again, I haven't combed the code for stray references...)

At least most of the ones from last year, for instance:

I am relatively new to licenses and issues surrounding them but I believe the MD2, MD4, MD5, SHA0, SHA1, SHA256, SHA512 and Tiger hashing algorithms that I wrote and placed in Deimos with a BSD style license are "RSA-free" as I wrote them using the RFC.
