* Update the AEGIS specification URL to the current draft
* std.crypto.auth: add AEGIS MAC
The Pelican-based authentication function of the AEGIS construction
can be used independently from authenticated encryption, as a faster
and more secure alternative to GHASH/POLYVAL/Poly1305.
We already expose GHASH, POLYVAL and Poly1305 for use outside AES-GCM
and ChaChaPoly, so there are no reasons not to expose the MAC from AEGIS
as well.
Like other 128-bit hash functions, finding a collision only requires
~2^64 attempts or inputs, which may still be acceptable for many
practical applications.

License
The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
