From 5730f061642c1b3065eabd55f8748a3cd43f65b4 Mon Sep 17 00:00:00 2001 From: "Joe Richey joerichey@google.com" Date: Tue, 23 May 2017 19:12:26 -0700 Subject: vendor: add in external packages for use with CLI crypto/ssh/terminal gets us information about the terminal, such as its dimensions and state. It also allows us to manipulate the terminal. For example, we can put the terminal in raw mode when a passphrase needs to be entered. This commit also add the github.com/urfave/cli package which we will use to write the command line tool component of fscrypt. This tool allows for us to easily use commands and subcommands. Note that this is actually the upstream repository with two PRs applied: https://github.com/urfave/cli/pull/629 https://github.com/urfave/cli/pull/630 They fix bugs in the handling of custom usage errors.
