(Make sure you have installed [Node](http://nodejs.org/download/).)\n\n```\nnpm install --save-dev uglify-save-license\n```\n\n## Usage\n\nFirst of all, load `uglify-save-license` module.\n\n```javascript\nvar saveLicense = require('uglify-save-license');\n```\n\n### Use with [UglifyJS](https://github.com/mishoo/UglifyJS2)\n\nPass this module to the [`comments` option](https://github.com/mishoo/UglifyJS2#keeping-comments-in-the-output).\n\n```javascript\nvar result = UglifyJS.minify('file1.js', {\n  output: {\n    comments: saveLicense\n  }\n});\n```\n\n### Use with [grunt-contrib-uglify](https://github.com/gruntjs/grunt-contrib-uglify)\n\nPass this module to the [`preserveComments` option](https://github.com/gruntjs/grunt-contrib-uglify#preservecomments).\n\n```javascript\ngrunt.initConfig({\n  uglify: {\n    my_target: {\n      options: {\n        preserveComments: saveLicense\n      },    \n      src: ['src/app.js'],\n      dest: 'dest/app.min.js' \n    }\n  }\n});\n```\n\n## How it works\n\n*uglify-save-license* checks each [comment token](http://lisperator.net/uglifyjs/ast#tokens) of a JavaScript file.\nThe comment will be regarded as a license statement and preserved after compression, if it meets at least one of the following requirements:\n\n1. The comment is in the *first* line of a file.\n2. [The regexp for license statement](./uglify-save-license.js#L7) matches the string of the comment. It matches, for example, `MIT` and `Copyright`.\n3. There is a comment at the *previous* line, and it matches 1. 2. or 3.\n\n## Examples\n\n### CLI tool example\n\n#### Main script (`uglify-example.js`)\n\n```javascript\n#!/usr/bin/env node\n\nvar UglifyJS    = require('uglify-js'),\n    saveLicense = require('uglify-save-license');\n\nvar minified = UglifyJS.minify(process.argv[2], {\n  output: {\n    comments: saveLicense\n  }\n}).code;\n\nconsole.log(minified);\n```\n\n#### Target file\n\n```javascript\n// First line\n\n// (c) 2014 John  <- contains '(c)'\n// The previous line is preserved\n\n// This line won't be preserved.\n(function(win, doc) {\n  var str = 'Hello World! :' + doc.title;\n\n  // This line will not, too.\n  console.log(str);\n}(window, document));\n```\n\n#### Command\n\n```\nnode uglify-example.js <target filename>\n```\n\n#### Output\n\n```javascript\n// First line\n// (c) 2014 John  <- contains '(c)'\n// The previous line is preserved\n!function(o,l){var n=\"Hello World! :\"+l.title;console.log(n)}(window,document);\n```\n\n### [Gruntfile.coffee](http://gruntjs.com/getting-started#the-gruntfile) example\n\n```coffeescript\nmodule.exports = (grunt) ->\n\n  grunt.loadNpmTasks 'grunt-contrib-uglify'\n  grunt.loadNpmTasks 'grunt-contrib-concat'\n  grunt.loadNpmTasks 'grunt-contrib-clean'\n  \n  grunt.initConfig\n    uglify:\n      target:\n        options:\n          preserveComments: require 'uglify-save-license'\n        files: [\n          expand: true\n          flatten: true\n          cwd: 'path/to/src'\n          src: ['**/*.js']\n          dest: 'tmp/'\n        ]\n\n    concat:\n      js:\n        src: ['tmp/*.js']\n        dest: 'path/to/build/app.js'\n\n    clean:\n      tmpdir: ['tmp']\n\n  grunt.registerTask 'default' ['uglify', 'concat', 'clean']\n```\n\n## Acknowledgements\n\n*uglify-save-license* is inspired by [grunt-license-saver](https://github.com/kyo-ago/grunt-license-saver) and I used it as reference.\nThanks, [kyo-ago](https://github.com/kyo-ago).\n\n## License\n\nCopyright (c) 2013 - 2014 [Shinnosuke Watanabe](https://github.com/shinnn)\n\nLicensed under [the MIT license](./LICENSE).\n",
