 This page tells you how to use the _pub_ tool (`bin/pub`)
 to manage Dart packages. A Dart package is simply
 a directory containing any number of Dart libraries and their dependencies.
 
 The `bin/pub` executable is in the [Dart SDK](/docs/sdk/).
 You can either [download the SDK separately](/docs/sdk/#download)
 or get it as part of the [Dart Editor package](/docs/editor/#download).

 This command creates a _packages_ directory inside the current directory,
 cloning the git repositories into the packages directory.
 
 The packages directory also contains any _transitive
 dependencies_. 
 For example, if the `awesome` package is dependent on the `sweet` package, 
 the pub tool will also download and install the `sweet` package.
 
 ## Using libraries from the SDK

 Not all libraries that ship with the SDK are available in the `dart:`
 namespace. To use those libraries (for example, unittest) in your app,
 add an `sdk` source to your `pubspec.yaml` file. For example:
 
 {% highlight yaml %}
 dependencies:
   unittest:
     sdk: unittest

 If you use the `pub install` command, the packages directory is created
 for you next to the pubspec.yaml file.
 
 ### Mapping packages for the Dart Editor
 
 To help the Dart Editor understand how to find packages, go to Preferences 
 and point the "Package directory" to `/path/to/your/app/packages`.

 ### Mapping packages for the Dart VM
 
 For command-line Dart applications that use packages, use the
 `--package-root` option to specify the packages location.
 
 For example:
 
 {% highlight bash %}
 $DART_SDK/bin/dart --package-root=./packages/ app.dart
 {% endhighlight %}
 
 Note the required trailing slash when specifying the `./packages/` directory.
 
 ## Importing libraries from packages
 
 To import libraries found in packages, use the `package:` prefix.
 
 {% highlight dart %}
 #import('package:awesome/awesome.dart');
 {% endhighlight %}
 
 ## Additional options
 
 Run `$DART_SDK/bin/pub --help` for a list of commands.
