// Package platforms provides a toolkit for normalizing, matching and
// specifying container platforms.
//
// Centered around OCI platform specifications, we define a string-based
// specifier syntax that can be used for user input. With a specifier, users
// only need to specify the parts of the platform that are relevant to their
// context, providing an operating system or architecture or both.
//
// How do I use this package?
//
// The vast majority of use cases should simply use the match function with
// user input. The first step is to parse a specifier into a matcher:
//
// m, err := Parse("linux")
// if err != nil { ... }
//
// Once you have a matcher, use it to match against the platform declared by a
// component, typically from an image or runtime. Since extracting an images
// platform is a little more involved, we'll use an example against the
// platform default:
//
// if ok := m.Match(Default()); !ok { /* doesn't match */ }
//
// This can be composed in loops for resolving runtimes or used as a filter for
// fetch and select images.
//
// More details of the specifier syntax and platform spec follow.
//
// Declaring Platform Support
//
// Components that have strict platform requirements should use the OCI
// platform specification to declare their support. Typically, this will be
// images and runtimes that should make these declaring which platform they
// support specifically. This looks roughly as follows:
//
// type Platform struct {
// Architecture string
// OS string
// Variant string
// }
//
// Most images and runtimes should at least set Architecture and OS, according
// to their GOARCH and GOOS values, respectively (follow the OCI image
// specification when in doubt). ARM should set variant under certain
// discussions, which are outlined below.
//
// Platform Specifiers
//
// While the OCI platform specifications provide a tool for components to
// specify structured information, user input typically doesn't need the full
// context and much can be inferred. 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. The most common arm version, v7, is represented without the variant
// unless it is explicitly provided. This is treated as equivalent to armhf. A
// previous architecture, armel, will be normalized to arm/v6.
//
// While these normalizations are provided, their support on arm platforms has
