<div class="section-body-1">
<p>Boost provides free peer-reviewed portable C++
source libraries.</p>
<p>We emphasize 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 <a href=
"more/license_info.html">Boost license</a> encourages
both commercial and non-commercial use.</p>
<p>We aim to establish "existing practice" and
provide reference implementations so that Boost
libraries are suitable for eventual standardization.
Ten Boost libraries are already included in the
<a href="http://www.open-std.org/jtc1/sc22/wg21">C++
Standards Committee's</a> Library Technical Report (
<a href=
"http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1745.pdf">
TR1</a>) as a step toward becoming part of a future
C++ Standard. More Boost libraries are proposed for
the upcoming <a href=
"http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1810.html">
TR2</a>.</p>
<p class="note"><span class="note-label">Getting
started:</span> <span class="note-body">Boost works
on almost any modern operating system, including UNIX
and Windows variants. Follow the <a href=
"more/getting_started.html">Getting Started Guide</a>
to download and install Boost. Popular Linux and Unix
distributions such as <a href=
"http://fedora.redhat.com/">Fedora</a>, <a href=
"http://www.debian.org/">Debian</a>, and <a href=
"http://www.netbsd.org/">NetBSD</a> include pre-built
Boost packages. Boost may also already be available
on your organization's internal web
server.</span></p>

"note-body">The <a href=
"more/background.html">Background Information

<h4>Supported Compilers</h4>
<p>Boost is tested on a wide range of compilers and
platforms. Since Boost libraries rely on modern C++
features not available in all compilers, not all
Boost libraries will work with every compiler. The
following compilers and platforms have been
extensively tested with Boost, although many other
compilers and platforms will work as well. For more
information, see the <a href=
"http://www.boost.org/regression/release/user/">regression
test results</a>.</p>

problems with Visual C++ 8.0 beta, and the presence
of a variety of pre-release compiler builds, we are
unable to guarantee compatibility until the final
compiler is released.</li>
