;; According to https://golang.org/doc/install/gccgo, gccgo-4.8.2 includes a

AVX2 for Intel and ARM64 for ARM.  On AVX512 it provides an up to 8x
improvement (over 3 GB/s per core) in comparison to AVX2.

This package is designed as a replacement for @command{crypto/sha256}.  For
Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also
supported).  For ARM CPUs with the Cryptography Extensions, advantage is taken
of the SHA2 instructions resulting in a massive performance improvement.

This package uses Golang assembly.  The AVX512 version is based on the Intel's
\"multi-buffer crypto library for IPSec\" whereas the other Intel
implementations are described in \"Fast SHA-256 Implementations on Intel
Architecture Processors\" by J. Guilford et al.")

directory without the use of @command{cgo}, so the library can be used in
cross-compilation environments.

Usage is simple, just call homedir.Dir() to get the home directory for a user,
and homedir.Expand() to expand the @command{~} in a path to the home
directory.

Why not just use @command{os/user}?  The built-in @command{os/user} package
requires cgo on Darwin systems.  This means that any Go code that uses that
package cannot cross compile.  But 99% of the time the use for
@command{os/user} is just to retrieve the home directory, which we can do for
the current user without cgo.  This library does that, enabling
cross-compilation.")
