-The header `<boost/static_assert.hpp>` supplies two macros:
-
-   BOOST_STATIC_ASSERT(x)
-   BOOST_STATIC_ASSERT_MSG(x, msg)
-   
-Both generate a compile time error message if the integral-constant-expression `x`

+The header `<boost/static_assert.hpp>` supplies a single macro `BOOST_STATIC_ASSERT(x)`, 
+which generates a compile time error message if the integral-constant-expression `x`
+is not true. In other words it is the compile time equivalent of the assert macro; 
 this is sometimes known as a "compile-time-assertion", but will be called a 
 "static assertion" throughout these docs. Note that if the condition is `true`,

+then the macro will generate neither code nor data - and the macro can also 
 be used at either namespace, class or function scope. When used in a template, 
 the static assertion will be evaluated at the time the template is instantiated; 
-this is particularly useful for validating template parameters.
-
-If the C++0x `static_assert` feature is available, both macros will use it.
-For `BOOST_STATIC_ASSERT(x)`, the error message with be a stringized version of `x`.
-For `BOOST_STATIC_ASSERT_MSG(x, msg)`, the error message will be the `msg` string.
-
-If the C++0x `static_assert` feature is not available, `BOOST_STATIC_ASSERT_MSG(x, msg)`

 One of the aims of `BOOST_STATIC_ASSERT` is to generate readable error messages.
