  <pre dir="ltr">The descriptions for portable_name() and portable_directory_name()
appear to be at odds.

portable_name() : ... &amp;&amp; (name is &quot;.&quot; or &quot;..&quot;, and the first character
not a period or hyphen)

portable_directory_name(): ... &amp;&amp; (name is &quot;.&quot; or &quot;..&quot; &nbsp;or contains no periods)

Should portable_name() be &quot;... &amp;&amp; (name is &quot;.&quot; or &quot;..&quot;, or contains no
periods) &amp;&amp; (first character not a hyphen)&quot;? &nbsp;Maybe I'm missing
something?</pre>

  <pre dir="ltr">- uncomplete(p, base)

My pet request. &nbsp;It may be useful to simplify other functions as well,
since there's no current way to go from an absolute path to a relative
one, meaning that most functions need to handle relative ones even
when that might not be natural. &nbsp;With this functionality,
preconditions requiring absolute paths would be less onerous.

&nbsp; &nbsp;Precondition: p.is_absolute() &amp;&amp; base.is_absolute()

&nbsp; &nbsp;Effects: Extracts a path, rp, from p relative to base such that
canonical(p) == complete(rp, base). &nbsp;Any &quot;..&quot; path elements in rp form
a prefix.

&nbsp; &nbsp;Returns: The extracted path.

&nbsp; &nbsp;Postconditions: For the returned path, rp, rp.is_relative() ==
(p.root_name() == b.root_name()).

[Notes: This function simplifies paths by omitting context. &nbsp;It is
particularly useful for serializing paths such that it can be usefully
moved between hosts where the context may be different, such as inside
source control trees. &nbsp;It can also be helpful for display to users,
such as in shells where paths are often shown relative to $HOME.

In the presence of symlinks, the result of this function may differ
between implementations, as some may expand symlinks that others may
not. &nbsp;The simplest implementation uses canonical to expand both p and
base, then removes the common prefix and prepends the requisite &quot;..&quot;
elements. &nbsp;Smarter implementations will avoid expanding symlinks
unnecessarily. &nbsp;No implementation is expected to discover new symlinks
to return paths with fewer elements.]</pre>

  <li>Reorganize files - delete examples that no longer apply.</li>
  <li>Should minimal.css be changed to used relative font sizes? See

  <li style="font-size: 10pt">Behavior of root_path() has been changed. Change

<h2>Code</h2>
<h3>All</h3>
<ul>
  <li style="font-size: 10pt">Move semantics.</li>
  <li style="font-size: 10pt">Use BOOST_DELETED, BOOST_DEFAULTED, where 
  appropriate.</li>
  <li style="font-size: 10pt">Other C++0x features.</li>
</ul>
<h3>Class path</h3>
<ul>
  <li>Windows, POSIX, conversions for char16_t, char32_t for C++0x compilers.</li>
  <li>Add Windows Alternate Data Stream test cases. See http://en.wikipedia.org/wiki/NTFS 
  Features.</li>
  <li>Add test case: relational operators on paths differing only in trailing 
  separator. Rationale?</li>
  <li>Provide the name check functions for more character types? Templatize? 
  take a path argument?</li>
  <li style="font-size: 10pt">Add codepage 936/950/etc test cases.</li>
  <li style="font-size: 10pt">Should UDT's be supported?</li>
  <li style="font-size: 10pt">Should path iteration to a separator result in:<br>
  -- the actual separator used<br>
  -- the preferred separator<br>
  -- the generic separator &lt;-- makes it easier to write portable code<br>
  -- a dot</li>
</ul>
<h3>Operations</h3>
<ul>
  <li>Would complete(), system_complete() be clearer if renamed absolute(), 
  absolute_system() (or absolute_native())?</li>
  <li>Review all operations.cpp code for race conditions similar to #2925. Fix 
  or document.</li>
  <li>Enable all BOOST_FILESYSTEM_NO_DEPRECATED code.</li>
  <li>rename and remove names are problems. If users says &quot;using 
  namespace boost::filesystem&quot;<br>
  and some header included stdio, there is just too much chance of silent error.</li>
  <li>create_directories error handling needs work.</li>
  <li>Fold convenience.hpp into operations.hpp</li>
  <li>Two argument recursive_directory_iterator ctor isn't recognizing throws(). 
  Would it be better to fold into a single two argument ctor with default?</li>
  <li>Add the push_directory class from tools/release/required_files.cpp</li>
</ul>

<h3>Miscellaneous</h3>
<ul>
  <li style="font-size: 10pt"><i>Regular</i> classes need hash functions.</li>
