    [Okio](https://github.com/square/okio), an I/O library that makes it easier
    to access, store and process data. Using this library internally makes OkHttp
    faster while consuming less memory. You can write a `RequestBody` as an Okio
    `BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard
    `InputStream` and `OutputStream` access is also available.

==== Substituting a dependency with attributes

Let's imagine that you want to substitute a platform dependency with a regular dependency.
This means that the library you are consuming declared something like this:

.An incorrect dependency on a platform
====

//
// will end in context{stateURL, delimSpaceOrTagEnd, ...}.
// There are two transitions that happen when the 'x' is seen:
// (1) Transition from a before-value state to a start-of-value state without
//
//	consuming any character.
//
// (2) Consume 'x' and transition past the first value character.
// In this case, nudging produces the context after (1) happens.
func nudge(c context) context {
	switch c.state {
	case stateTag:

The component metadata rules API allows you to <<component_metadata_rules.adoc#sec:component_metadata_rules_details,access Ivy configurations>> and create variants based on them.
If you know that all the Ivy modules your are consuming have been published with Gradle without further customizations of the `ivy.xml` file, you can add the following rule to your build:
