+
+[section:intro Overview and Tutorial]
+
+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`
+is not true. In other words, they are 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 macros will generate neither code nor data - and the macros 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)`
+will be treated as `BOOST_STATIC_ASSERT(x)`.
+
+The material that follows assumes the C++0x `static_assert` feature is not available.
+
+One of the aims of `BOOST_STATIC_ASSERT` is to generate readable error messages. 
+These immediately tell the user that a library is being used in a manner that 
+is not supported. While error messages obviously differ from compiler to compiler, 
+but you should see something like: 
+
+   Illegal use of STATIC_ASSERTION_FAILURE<false>
+
+Which is intended to at least catch the eye!
+
+You can use `BOOST_STATIC_ASSERT` at any place where you can place a declaration, 
+that is at class, function or namespace scope, this is illustrated by the 
+following examples:
+
+[section:namespace Use at namespace scope.]
+
+The macro can be used at namespace scope, if there is some requirement must 
+always be true; generally this means some platform specific requirement. 
+Suppose we require that `int` be at least a 32-bit integral type, and that `wchar_t` 
+be an unsigned type. We can verify this at compile time as follows:
+
+   #include <climits>
+   #include <cwchar>
+   #include <limits>
+   #include <boost/static_assert.hpp>
+
+   namespace my_conditions {
+
+      BOOST_STATIC_ASSERT(std::numeric_limits<int>::digits >= 32);
+      BOOST_STATIC_ASSERT(WCHAR_MIN >= 0);
+
+   } // namespace my_conditions
+
+The use of the namespace my_conditions here requires some comment. 
+The macro `BOOST_STATIC_ASSERT` works by generating an typedef declaration, 
+and since the typedef must have a name, the macro generates one automatically by 
+mangling a stub name with the value of `__LINE__`. When `BOOST_STATIC_ASSERT` is 
+used at either class or function scope then each use of `BOOST_STATIC_ASSERT` 
+is guaranteed to produce a name unique to that scope (provided you only use 
+the macro once on each line). However when used in a header at namespace 
+scope, that namespace can be continued over multiple headers, each of which 
+may have their own static assertions, and on the "same" lines, thereby generating 
+duplicate declarations. In theory the compiler should silently ignore duplicate 
+typedef declarations, however many do not do so (and even if they do they are 
+entitled to emit warnings in such cases). To avoid potential problems, if you 
+use `BOOST_STATIC_ASSERT` in a header and at namespace scope, then enclose 
+them in a namespace unique to that header.
+
+[endsect]
+
+[section:function Use at function scope]
+
+The macro is typically used at function scope inside template functions, 
+when the template arguments need checking. Imagine that we have an 
+iterator-based algorithm that requires random access iterators. 
+If the algorithm is instantiated with iterators that do not meet our 
+requirements then an error will be generated eventually, but this may 
+be nested deep inside several templates, making it hard for the user to 
+determine what went wrong. One option is to add a static assertion at 
+the top level of the template, in that case if the condition is not met, 
+then an error will be generated in a way that makes it reasonably obvious to 
+the user that the template is being misused.
+
+   #include <iterator>
+   #include <boost/static_assert.hpp>
+   #include <boost/type_traits.hpp>
+
+   template <class RandomAccessIterator >
+   RandomAccessIterator foo(RandomAccessIterator from, 
+                            RandomAccessIterator to)
+   {
+      // this template can only be used with
+      // random access iterators...
+      typedef typename std::iterator_traits< 
+            RandomAccessIterator >::iterator_category cat;
+      BOOST_STATIC_ASSERT(
+         (boost::is_convertible<
+            cat, 
+            const std::random_access_iterator_tag&>::value));
+      //
+      // detail goes here...
+      return from;
+   }
+
+A couple of footnotes are in order here: the extra set of parenthesis around the 
+assert, is to prevent the comma inside the `is_convertible` template being 
+interpreted by the preprocessor as a macro argument separator; the target type 
+for `is_convertible` is a reference type, as some compilers have problems 
+using `is_convertible` when the conversion is via a user defined constructor 
+(in any case there is no guarantee that the iterator tag classes are 
+copy-constructible).
+
+[endsect]
+
+[section:class Use at class scope]
+
+The macro is typically used inside classes that are templates. 
+Suppose we have a template-class that requires an unsigned integral type with 
+at least 16-bits of precision as a template argument, we can achieve this 
+using something like this:
+
+   #include <limits>
+   #include <boost/static_assert.hpp>
+
+   template <class UnsignedInt>
+   class myclass
+   {
+   private:
+      BOOST_STATIC_ASSERT((std::numeric_limits<UnsignedInt>::digits >= 16)
+                           && std::numeric_limits<UnsignedInt>::is_specialized
+                           && std::numeric_limits<UnsignedInt>::is_integer
+                           && !std::numeric_limits<UnsignedInt>::is_signed);
+   public:
+      /* details here */
+   };
+
+[endsect]
+
+[section:templates Use in templates]
+
+Normally static assertions when used inside a class or function template, 
+will not be instantiated until the template in which it is used is instantiated.  
+However, there is one potential problem to watch out for: if the static assertion 
+is not dependent upon one or more template parameters, then the compiler is 
+permitted to evaluate the static assertion at the point it is first seen, 
+irrespective of whether the template is ever instantiated, for example:
+
+   template <class T>
+   struct must_not_be_instantiated
+   {   
+      BOOST_STATIC_ASSERT(false);
+   };
+
+Will produce a compiler error with some compilers (for example Intel 8.1 
+or gcc 3.4), regardless of whether the template is ever instantiated.  A 
+workaround in cases like this is to force the assertion to be dependent 
+upon a template parameter:
+
+   template <class T>
+   struct must_not_be_instantiated
+   {   
+      // this will be triggered if this type is instantiated
+      BOOST_STATIC_ASSERT(sizeof(T) == 0); 
+   };
+
+
+[endsect]
+
+[endsect]
+
+[section:how How it works]
+
+`BOOST_STATIC_ASSERT` works as follows. There is class `STATIC_ASSERTION_FAILURE`
+ which is defined as:
+
+   namespace boost{
+
+   template <bool> struct STATIC_ASSERTION_FAILURE;
+
+   template <> struct STATIC_ASSERTION_FAILURE<true>{};
+
+   }
+
+The key feature is that the error message triggered by the undefined 
+expression `sizeof(STATIC_ASSERTION_FAILURE<0>)`, tends to be consistent 
+across a wide variety of compilers. The rest of the machinery of 
+`BOOST_STATIC_ASSERT` is just a way to feed the `sizeof` expression into a `typedef`. 
+The use of a macro here is somewhat ugly; however boost members have spent 
+considerable effort trying to invent a static assert that avoided macros, 
+all to no avail. The general conclusion was that the good of a static assert 
+working at namespace, function, and class scope outweighed the ugliness of a macro.
