+
+  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).  
+  [API documentation](http://tj.github.com/commander.js/)
+
+
+## Installation
+
+    $ npm install commander --save
+
+## Option parsing
+
+ Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-p, --peppers', 'Add peppers')
+  .option('-P, --pineapple', 'Add pineapple')
+  .option('-b, --bbq-sauce', 'Add bbq sauce')
+  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
+  .parse(process.argv);
+
+console.log('you ordered a pizza with:');
+if (program.peppers) console.log('  - peppers');
+if (program.pineapple) console.log('  - pineapple');
+if (program.bbqSauce) console.log('  - bbq');
+console.log('  - %s cheese', program.cheese);
+```
+
+ Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
+
+Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. 
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .option('--no-sauce', 'Remove sauce')
+  .parse(process.argv);
+
+console.log('you ordered a pizza');
+if (program.sauce) console.log('  with sauce');
+else console.log(' without sauce');
+```
+
+## Coercion
+
+```js
+function range(val) {
+  return val.split('..').map(Number);
+}
+
+function list(val) {
+  return val.split(',');
+}
+
+function collect(val, memo) {
+  memo.push(val);
+  return memo;
+}
+
+function increaseVerbosity(v, total) {
+  return total + 1;
+}
+
+program
+  .version('0.1.0')
+  .usage('[options] <file ...>')
+  .option('-i, --integer <n>', 'An integer argument', parseInt)
+  .option('-f, --float <n>', 'A float argument', parseFloat)
+  .option('-r, --range <a>..<b>', 'A range', range)
+  .option('-l, --list <items>', 'A list', list)
+  .option('-o, --optional [value]', 'An optional value')
+  .option('-c, --collect [value]', 'A repeatable value', collect, [])
+  .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
+  .parse(process.argv);
+
+console.log(' int: %j', program.integer);
+console.log(' float: %j', program.float);
+console.log(' optional: %j', program.optional);
+program.range = program.range || [];
+console.log(' range: %j..%j', program.range[0], program.range[1]);
+console.log(' list: %j', program.list);
+console.log(' collect: %j', program.collect);
+console.log(' verbosity: %j', program.verbose);
+console.log(' args: %j', program.args);
+```
+
+## Regular Expression
+```js
+program
+  .version('0.1.0')
+  .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
+  .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
+  .parse(process.argv);
+  
+console.log(' size: %j', program.size);
+console.log(' drink: %j', program.drink);
+```
+
+## Variadic arguments
+
+ The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you have to
+ append `...` to the argument name.  Here is an example:
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .command('rmdir <dir> [otherDirs...]')
+  .action(function (dir, otherDirs) {
+    console.log('rmdir %s', dir);
+    if (otherDirs) {
+      otherDirs.forEach(function (oDir) {
+        console.log('rmdir %s', oDir);
+      });
+    }
+  });
+
+program.parse(process.argv);
+```
+
+ An `Array` is used for the value of a variadic argument.  This applies to `program.args` as well as the argument passed
+ to your action as demonstrated above.
+
+## Specify the argument syntax
+
+```js
+#!/usr/bin/env node
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .arguments('<cmd> [env]')
+  .action(function (cmd, env) {
+     cmdValue = cmd;
+     envValue = env;
+  });
+
+program.parse(process.argv);
+
+if (typeof cmdValue === 'undefined') {
+   console.error('no command given!');
+   process.exit(1);
+}
+console.log('command:', cmdValue);
+console.log('environment:', envValue || "no environment given");
+```
+Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
+
+## Git-style sub-commands
+
+```js
+// file: ./examples/pm
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .command('install [name]', 'install one or more packages')
+  .command('search [query]', 'search with optional query')
+  .command('list', 'list packages installed', {isDefault: true})
+  .parse(process.argv);
+```
+
+When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.  
+The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
+
+Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the option from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+### `--harmony`
+
+You can enable `--harmony` option in two ways:
+* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
+* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
+
+## Automated --help
+
+ The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
+
+```  
+ $ ./examples/pizza --help
+
+   Usage: pizza [options]
+
+   An application for pizzas ordering
+
+   Options:
+
+     -h, --help           output usage information
+     -V, --version        output the version number
+     -p, --peppers        Add peppers
+     -P, --pineapple      Add pineapple
+     -b, --bbq            Add bbq sauce
+     -c, --cheese <type>  Add the specified type of cheese [marble]
+     -C, --no-cheese      You do not want any cheese
+
+```
+
+## Custom help
+
+ You can display arbitrary `-h, --help` information
+ by listening for "--help". Commander will automatically
+ exit once you are done so that the remainder of your program
+ does not execute causing undesired behaviours, for example
+ in the following executable "stuff" will not output when
+ `--help` is used.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-f, --foo', 'enable some foo')
+  .option('-b, --bar', 'enable some bar')
+  .option('-B, --baz', 'enable some baz');
+
+// must be before .parse() since
+// node's emit() is immediate
+
+program.on('--help', function(){
+  console.log('  Examples:');
+  console.log('');
+  console.log('    $ custom-help --help');
+  console.log('    $ custom-help -h');
+  console.log('');
+});
+
+program.parse(process.argv);
+
+console.log('stuff');
+```
+
+Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
+
+```
+
+Usage: custom-help [options]
+
+Options:
+
+  -h, --help     output usage information
+  -V, --version  output the version number
+  -f, --foo      enable some foo
+  -b, --bar      enable some bar
+  -B, --baz      enable some baz
+
+Examples:
+
+  $ custom-help --help
+  $ custom-help -h
+
+```
+
+## .outputHelp(cb)
+
+Output help information without exiting.
+Optional callback cb allows post-processing of help text before it is displayed.
+
+If you want to display help by default (e.g. if no command was provided), you can use something like:
+
+```js
+var program = require('commander');
+var colors = require('colors');
+
+program
+  .version('0.1.0')
+  .command('getstream [url]', 'get stream URL')
+  .parse(process.argv);
+
+if (!process.argv.slice(2).length) {
+  program.outputHelp(make_red);
+}
+
+function make_red(txt) {
+  return colors.red(txt); //display the help text in red on the console
+}
+```
+
+## .help(cb)
+
+  Output help information and exit immediately.
+  Optional callback cb allows post-processing of help text before it is displayed.
+
+## Examples
+
+```js
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-C, --chdir <path>', 'change the working directory')
+  .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
+  .option('-T, --no-tests', 'ignore test hook');
+
+program
+  .command('setup [env]')
+  .description('run setup commands for all envs')
+  .option("-s, --setup_mode [mode]", "Which setup mode to use")
+  .action(function(env, options){
+    var mode = options.setup_mode || "normal";
+    env = env || 'all';
+    console.log('setup for %s env(s) with %s mode', env, mode);
+  });
+
+program
+  .command('exec <cmd>')
+  .alias('ex')
+  .description('execute the given remote cmd')
+  .option("-e, --exec_mode <mode>", "Which exec mode to use")
+  .action(function(cmd, options){
+    console.log('exec "%s" using %s mode', cmd, options.exec_mode);
+  }).on('--help', function() {
+    console.log('  Examples:');
+    console.log();
+    console.log('    $ deploy exec sequential');
+    console.log('    $ deploy exec async');
+    console.log();
+  });
+
+program
+  .command('*')
+  .action(function(env){
+    console.log('deploying "%s"', env);
+  });
+
+program.parse(process.argv);
+```
