<p>The Bongo Project is creating fun and simple mail, calendaring and

contacts software: on top of a standards-based server stack; we're

innovating fresh and interesting web user interfaces for managing

personal communications. Bongo is providing an entirely free software

solution which is less concerned with the corporate mail scenario and

much more focused on how people want to organize their lives.</p>

<h2><a href="http://www.boost.org/">Boost</a></h2>

<p>Boost provides free peer-reviewed portable C++ source libraries.</p>

<p>Boost emphasizes libraries that work well with the C++ Standard

  Library.  Boost libraries are intended to be widely useful, and usable

  across a broad spectrum of applications.  The Boost license encourages

  both commercial and non-commercial use.</p>

<p>Boost aims to establish &ldquo;existing practice&rdquo; and provide

reference implementations so that Boost libraries are suitable for

eventual standardization. Ten Boost libraries are already included in the

C++ Standards Committee's Library Technical Report (TR1) as a step toward

becoming part of a future C++ Standard. More Boost libraries are proposed

for the upcoming TR2.</p>

<p>

Buildbot is a freely-licensed framework which enables software

developers to automate software build, test, and release processes for their

software projects.  First released in 2003, Buildbot is used by leading 

software projects around the world to automate all aspects of their 

software development cycle. </p>

<h2><a href="http://www.busybox.net">BusyBox</a></h2>

<p>BusyBox combines tiny versions of many common UNIX utilities into a

single small executable. It provides replacements for most of the

utilities you usually find in GNU fileutils, shellutils, etc. The

utilities in BusyBox generally have fewer options than their

full-featured GNU cousins; however, the options that are included

provide the expected functionality and behave very much like their GNU

counterparts. BusyBox provides a fairly complete environment for any

small or embedded system.</p>

<p>BusyBox has been written with size-optimization and limited

resources in mind. It is also extremely modular so you can easily

include or exclude commands (or features) at compile time. This makes

it easy to customize your embedded systems. To create a working
