+// 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
+// not yet been fully implemented and tested.
