-// Package context defines the Context type, which carries deadlines,
-// cancelation signals, and other request-scoped values across API boundaries
-// and between processes.
-//
-// Incoming requests to a server should create a Context, and outgoing calls to
-// servers should accept a Context. The chain of function calls between must
-// propagate the Context, optionally replacing it with a modified copy created
-// using WithDeadline, WithTimeout, WithCancel, or WithValue.
-//
-// Programs that use Contexts should follow these rules to keep interfaces
-// consistent across packages and enable static analysis tools to check context
-// propagation:
-//
-// Do not store Contexts inside a struct type; instead, pass a Context
-// explicitly to each function that needs it. The Context should be the first
-// parameter, typically named ctx:
-//
-// func DoSomething(ctx context.Context, arg Arg) error {
-// // ... use ctx ...
-// }
-//
-// Do not pass a nil Context, even if a function permits it. Pass context.TODO
-// if you are unsure about which Context to use.
-//
-// Use context Values only for request-scoped data that transits processes and
-// APIs, not for passing optional parameters to functions.
-//
-// The same Context may be passed to functions running in different goroutines;
-// Contexts are safe for simultaneous use by multiple goroutines.

-# Vendored Dependencies
-
-Dependencies are almost all vendored in at the standard Go `/vendor` path. This allows
-people to build go-ethereum using the standard toolchain without any particular package
-manager. It also plays nicely with `go get`, not requiring external code to be relied on.
-
-The one single dependent package missing from `vendor` is `golang.org/x/net/context`. As
-this is a package exposed via public library APIs, it must not be vendored as dependent
-code woulnd't be able to instantiate.
-
-To allow reproducible builds of go-ethereum nonetheless that don't need network access
-during build time to fetch `golang.org/x/net/context`, a version was copied into our repo
-at the very specific `/build/_vendor` path, which is added automatically by all CI build
-scripts and the makefile too.
