- The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:

+
+## 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('0.0.1')
+  .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('../');
+
+program
+  .version('0.0.1')
+  .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");
+```
+
+## Git-style sub-commands
+
+```js
+// file: ./examples/pm
+var program = require('..');
+
+program
+  .version('0.0.1')
+  .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:
+
+```
