To solve this problem, we introduced +// "specifiers". A specifier has the format +// `<os>|<arch>|<os>/<arch>[/<variant>]`. The user can provide either the +// operating system or the architecture or both. +// +// An example of a common specifier is `linux/amd64`. If the host has a default +// of runtime that matches this, the user can simply provide the component that +// matters. For example, if a image provides amd64 and arm64 support, the +// operating system, `linux` can be inferred, so they only have to provide +// `arm64` or `amd64`. Similar behavior is implemented for operating systems, +// where the architecture may be known but a runtime may support images from +// different operating systems. +// +// Normalization +// +// Because not all users are familiar with the way the Go runtime represents +// platforms, several normalizations have been provided to make this package +// easier to user. +// +// The following are performed for architectures: +// +// Value Normalized +// aarch64 arm64 +// armhf arm +// armel arm/v6 +// i386 386 +// x86_64 amd64 +// x86-64 amd64 +// +// We also normalize the operating system `macos` to `darwin`. +// +// ARM Support +// +// To qualify ARM architecture, the Variant field is used to qualify the arm +// version.
