/**
 * This annotation marks the extensions and top-level functions for working with [java.nio.file.Path] considered experimental.
 *
 * > Beware using the annotated API especially if you're developing a library, since your library might become binary incompatible
 * with the future versions of the standard library.
 *
 * Any usage of a declaration annotated with `@ExperimentalPathApi` must be accepted either by
 * annotating that usage with the [OptIn] annotation, e.g. `@OptIn(ExperimentalPathApi::class)`,
 * or by using the compiler argument `-Xopt-in=kotlin.io.path.ExperimentalPathApi`.
