[section Installing xpressive]

[h2 Getting xpressive]

There are three ways to get xpressive. The first and simplest is to download
the latest version of Boost. Just go to [@http://sf.net/projects/boost] and
follow the ["Download] link.

The second way is by downloading xpressive.zip at the
[@http://www.boost-consulting.com/vault/index.php?directory=Strings%20-%20Text%20Processing
Boost File Vault] in the ["Strings - Text Processing] directory. In addition to
the source code and the Boost license, this archive contains a copy of this
documentation in PDF format. This version will always be stable and at least as
current as the version in the latest Boost release. It may be more recent. The
version in the File Vault is always guaranteed to work with the latest official
Boost release.

The third way is by directly accessing the Boost Subversion repository.
Just go to [@http://svn.boost.org/trac/boost/] and follow the instructions there for
anonymous Subversion access. The version in Boost Subversion is unstable.

[h2 Building with xpressive]

Xpressive is a header-only template library, which means you don't need to alter
your build scripts or link to any separate lib file to use it. All you need to
do is `#include <boost/xpressive/xpressive.hpp>`. If you are only using static
regexes, you can improve compile times by only including `xpressive_static.hpp`.
Likewise, you can include `xpressive_dynamic.hpp` if you only plan on using
dynamic regexes.

If you would also like to use semantic actions or custom assertions with your
static regexes, you will need to additionally include `regex_actions.hpp`.

[h2 Requirements]

Xpressive requires Boost version 1.34.1 or higher.
