 ## SDK Concepts
 
 The Emscripten SDK is effectively a small package manager for tools that are used in conjunction with Emscripten. The following glossary highlights the important concepts to help understanding the internals of the SDK:
 
-* <b>Tool</b>: The basic unit of software bundled in the SDK. A Tool has a name and a version. For example, 'clang-3.2-32bit' is a Tool that contains the 32-bit version of the Clang v3.2 compiler.

-* <b>Active Tool/SDK</b>: Emscripten stores compiler configuration in a user-specific file <b>~/.emscripten</b>. This file points to paths for Emscripten, Python, Clang and so on. If the file ~/.emscripten is configured to point to a Tool in a specific directory, then that tool is denoted as being <b>active</b>. The Emscripten Command Prompt always gives access to the currently active Tools. This mechanism allows switching between different installed SDK versions easily.

 Emscripten SDK releases are no longer packaged or maintained for 32-bit Windows. If you want to run Emscripten on a 32-bit system, you can try manually building the compiler for 32-bit mode. Follow the steps in the above section "Building an Emscripten tag or branch from source" to get started.
