Cartage::CLI.extend do
  desc 'Work with the Manifest.txt file'
  long_desc <<-'DESC'
Commands that manage the Cartage manifest (Manifest.txt) and ignore
(.cartignore) files for a project.
  DESC
  command 'manifest' do |manifest|
    manifest.desc 'Check the Manifest.txt file against the current repository'
    manifest.long_desc <<-'DESC'
Compares the current Cartage manifest against what would be calculated. If
there is a difference, it will be displayed in unified ('diff -u') format and a
non-zero exit status will be returned.

The diff output can be suppressed by specifying -q on cartage:

    cartage -q manifest check
    DESC
    manifest.command 'check' do |check|
      check.action do |_global, _options, _args|
        cartage.manifest.check or
          fail Cartage::CLI::QuietExit, $?.exitstatus
      end
    end

    manifest.desc 'Install or update the .cartignore file'
    manifest.long_desc <<-'DESC'
Creates, replaces, or updates the Cartage ignore file (.cartignore). Will not
modify an existing .cartignore unless the --mode is overwrite or merge.
    DESC
    manifest.command 'cartignore' do |cartignore|
      cartignore.desc 'Overwrite or merge an existing .cartignore'
      cartignore.long_desc <<-'DESC'
Sets the mode for updating the ignore file. When --mode overwrite, the ignore
file will be replaced with the default ignore file contents. When --mode merge,
the existing ignore file will be merged with the default ignore file contents.
      DESC
