-Subject: [PATCH] Add env variable ARGON2_CFFI_USE_SSE2 to override sse2
- optimizations (#61)
-
-This is useful for cross compiling since platform.machine() is broken
-for cross builds.

-+Override Automatic SSE2 Detection
-+------------------------------------------
-+
-+If you set ``ARGON2_CFFI_USE_SSE2`` to ``1`` (and *only* ``1``), ``argon2-cffi`` will build with sse2 support.
-+
-+If you set ``ARGON2_CFFI_USE_SSE2`` to ``0`` (and *only* ``0``), ``argon2-cffi`` will build without sse2 support.
-+
-+This should generally only be used if the sse2 autodetection causes a compilation failure or if you are cross compiling.
