+ GCC 5.3 includes an implementation of the Filesystem library defined
+ by the technical specification ISO/IEC TS 18822:2015. Because this is
+ an experimental library extension, not part of the C++ standard, it
+ is implemented in a separate library,
+ <code class="filename">libstdc++fs.a</code>, and there is
+ no shared library for it. To use the library you should include
+ <code class="filename"><experimental/filesystem></code>
+ and link with <code class="option">-lstdc++fs</code>. The library implementation
+ is incomplete on non-POSIX platforms, specifically Windows support is
+ rudimentary.
+ </p><p>
+ Due to the experimental nature of the Filesystem library the usual
+ guarantees about ABI stability and backwards compatibility do not apply
+ to it. There is no guarantee that the components in any
+ <code class="filename"><experimental/xxx></code>
+ header will remain compatible between different GCC releases.

+ GCC 5.3 includes an implementation of the Filesystem library defined
+ by the technical specification ISO/IEC TS 18822:2015. Because this is
+ an experimental library extension, not part of the C++ standard, it
+ is implemented in a separate library,
+ <filename class="libraryfile">libstdc++fs.a</filename>, and there is
+ no shared library for it. To use the library you should include
+ <filename class="headerfile"><experimental/filesystem></filename>
+ and link with <option>-lstdc++fs</option>. The library implementation
+ is incomplete on non-POSIX platforms, specifically Windows support is
+ rudimentary.
+ </para>
+
+ <para>
+ Due to the experimental nature of the Filesystem library the usual
+ guarantees about ABI stability and backwards compatibility do not apply
+ to it. There is no guarantee that the components in any
+ <filename class="headerfile"><experimental/xxx></filename>
+ header will remain compatible between different GCC releases.
