<h4>Introduction</h4>
<div> The Boost Preprocessing library is a library of macros, with support
for preprocessor metaprogramming. The library supports both C++ and C
compilation. It does not depend on any other Boost libraries and therefore
may be used as a standalone library. </div>
<div> An excerpt from <i>C++ Template Metaprogramming: Concepts, Tools, and
Techniques from Boost and Beyond</i> by Dave Abrahams and Aleksey
Gurtovoy has been made <a href="AppendixA-AnIntroductiontoPreprocessorMetaprogramming.html"

This excerpt contains a basic introduction to the Preprocessor library and
preprocessor metaprogramming which may help users new to the library and
users interested in seeing some of the facilities offered by the library.

libraries and therefore may be used as a standalone library.<br>
<br>
The library assumes that the compiler supports variadic macros.
Since variadic macros are a C99 or C++11 feature the library
ostensibly requires at least compilation at those C or C++
standard levels. A number of compilers support variadic macros at
a lower level, so it still may be possible using the library at
the C++03 compilation level, as long as strict C++03 compliance is
not enforced.<br>
