-[Note: This "do-the-right-thing" rule allows users to write <code>exists("foo")</code>,

-is particularly important for the simple, script-like, programs which are an

-automatic conversion is not supported for such cases.
-The implementation technique is unspecified. One possible implementation
-technique, using
-<code>exists()</code> as an example, is:
- <blockquote>
- <pre>template <class Path>
- typename boost::enable_if<is_path<Path>,bool>::type exists(const path& p);
-inline bool exists(const path& p) { return exists<path>(p); }
-inline bool exists(const wpath& p) { return exists<wpath>(p); }</pre>

- to a <code>path</code> object via the appropriate <code>path</code> conversion
- constructor.   -- end note]

- <li>Better techniques for

- <li>Spelling out the overloads
- makes the text longer and harder to read without adding much benefit.</li>
- <li>More overloads will probably
- be needed for char16_t and char32_t (or whatever they end up being called),
- making it even less attractive to actually spell out each one. 
- </li>
- </ul>
-</blockquote>
-Implementations of functions described in this clause are permitted to call the applications
-program interface (API) provided by the operating system. If such an operating
-system API call results in an error, implementations
-shall report the error by throwing exception <code>basic_filesystem_error</code>,

-</blockquote>
-Functions commonly used in contexts
-where errors are not exceptional have overloads taking an additional argument of
-type <code>error_code& ec</code>. Such overloaded functions shall not throw exceptions. If an error occurs,
-<code>ec</code> shall be set to the
-error code reported by the operating system, otherwise <code>ec</code> shall be set to 0. If

+Functions in this library may throw exceptions as described in this section.
+Such exceptions are not explicitly described in each function's Throws
+element.
+Certain functions in this library are specified as having an argument of type
+<code>system::error_code& ec</code>. This argument determines how errors are

+underlying API results in an error that prevents the library function from
+meeting its specifications:
+<ul>
+ <li>If <code>&ec == &throws()</code>, the function throws an exception of type
+ <code>filesystem_error.</code></li>
+ <li>Otherwise, the function sets <code>ec</code> to an error_code representing
+ the error that occurred.</li>
+</ul>
+If an error does not occur and <code>&ec != &throws()</code>, <code>ec.clear()</code>
+is called.
+Certain failures are reported by throwing an exception, regardless of the
+value of the <code>ec</code> argument:
+<ul>
+ <li>Failure to allocate storage is reported as described in the C++ standard,
