-// SequenceMatcher compares sequence of strings. The basic
-// algorithm predates, and is a little fancier than, an algorithm
-// published in the late 1980's by Ratcliff and Obershelp under the
-// hyperbolic name "gestalt pattern matching". The basic idea is to find
-// the longest contiguous matching subsequence that contains no "junk"
-// elements (R-O doesn't address junk). The same idea is then applied
-// recursively to the pieces of the sequences to the left and to the right
-// of the matching subsequence. This does not yield minimal edit
-// sequences, but does tend to yield matches that "look right" to people.
-//
-// SequenceMatcher tries to compute a "human-friendly diff" between two
-// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
-// longest *contiguous* & junk-free matching subsequence. That's what
-// catches peoples' eyes. The Windows(tm) windiff has another interesting
-// notion, pairing up elements that appear uniquely in each sequence.
-// That, and the method here, appear to yield more intuitive difference
-// reports than does diff. This method appears to be the least vulnerable
-// to synching up on blocks of "junk lines", though (like blank lines in
-// ordinary text files, or maybe "" lines in HTML files). That may be
-// because this is the only method of the 3 that has a *concept* of
-// "junk" .
-//
-// Timing: Basic R-O is cubic time worst case and quadratic time expected
-// case. SequenceMatcher is quadratic time for the worst case and has
-// expected-case behavior dependent in a complicated way on how many
-// elements the sequences have in common; best case time is linear.

-// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
-//
-// Example Usage
-//
-// The following is a complete example using assert in a standard test function:
-// import (
-// "testing"
-// "github.com/stretchr/testify/assert"
-// )
-//
-// func TestSomething(t *testing.T) {
-//
-// var a string = "Hello"
-// var b string = "Hello"
-//
-// assert.Equal(t, a, b, "The two words should be the same.")
-//
-// }
-//
-// if you assert many times, use the format below:
-//
-// import (
-// "testing"
-// "github.com/stretchr/testify/assert"
-// )
-//
-// func TestSomething(t *testing.T) {
-// assert := assert.New(t)
-//
-// var a string = "Hello"
-// var b string = "Hello"
-//
-// assert.Equal(a, b, "The two words should be the same.")
-// }
-//
-// Assertions
-//
-// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
-// All assertion functions take, as the first argument, the `*testing.T` object provided by the
-// testing framework. This allows the assertion funcs to write the failings and other details to
-// the correct place.
-//
-// Every assertion function also takes an optional string message as the final argument,
-// allowing custom error messages to be appended to the message the assertion method outputs.

-// Most multiplications by 2 and 19 are 32-bit precomputations;

-// There is one remaining multiplication by 19 in the carry chain;
-// one *19 precomputation can be merged into this,
-// but the resulting data flow is considerably less clean.
-//
-// There are 12 carries below.

-// Can get away with 11 carries, but then data flow is much deeper.
-//
-// With tighter constraints on inputs can squeeze carries into int32.

-// There are some differences between CRYPTOGAMS code and this one. The round
-// loop for "_int" isn't the same as the original. Some adjustments were
-// necessary because there are less vector registers available. For example, some
-// X variables (r12, r13, r14, and r15) share the same register used by the
-// counter. The original code uses ctr to name the counter. Here we use CNT
-// because golang uses CTR as the counter register name.

-// Package poly1305 implements Poly1305 one-time message authentication code as
-// specified in https://cr.yp.to/mac/poly1305-20050329.pdf.
-//
-// Poly1305 is a fast, one-time authentication function. It is infeasible for an
-// attacker to generate an authenticator for a message without the key. However, a
-// key must only be used for a single message. Authenticating two different
-// messages with the same key allows an attacker to forge authenticators for other
-// messages with the same key.
-//
-// Poly1305 was originally coupled with AES in order to make Poly1305-AES. AES was
-// used with a fixed key in order to generate one-time keys from an nonce.
-// However, in this package AES isn't used and the one-time key is specified
-// directly.
-package poly1305 // import "golang.org/x/crypto/poly1305"

-
-// New returns a new MAC computing an authentication
-// tag of all data written to it with the given key.
-// This allows writing the message progressively instead
-// of passing it as a single slice. Common users should use
-// the Sum function instead.
-//
-// The key must be unique for each message, as authenticating
-// two different messages with the same key allows an attacker
-// to forge messages at will.

-Package ssh implements an SSH client and server.

-SSH is a transport security protocol, an authentication protocol and a

-protocol is a remote shell and this is specifically implemented. However,
-the multiplexed nature of SSH is exposed to users that wish to support
-others.

-
-This package does not fall under the stability promise of the Go language itself,

-// 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 {
