335          <li class="new">hide the make_fragments declaration in private sections. This was not true previously. A make_fragment declaration installed in a private section will now be hidden to clients.</li>
336          <li class="bug">convert ${} into $() syntax for tag makefiles on Windows. This actually reverts to a feature of an old CMT version which had disappeared. This was causing a problem since the ${} syntax is not understood by nmake</li>
337          <li class="new">add a command "cmt show use_paths &lt;target&gt;" to display all possible paths to the target package. This is useful to understand how a given package is reached, for instance when it is desired to cut the use relationship and make it private somewhere in the graph.</li>
338          <li class="new">add a command "cmt show cycles" to display circular dependencies in the use graph.</li>
339          <li class="new">provide a binary RPM for CMT itself (only for redhat 7.2 distribution). It is downloadable from the usual Download page and provide a complete installation of CMT (including make fragments, binary, etc..). It is a relocatable RPM (install it using the --relocate option). (See the install WEB page for complete notice)</li>
340          <li class="new">Add an extended script to retrieve information about Linux version (cmt_linux_version.sh). It supports Redhat, Debian, Suse. It is used to compute the cmt_system_version macro (contributions from Clark McGrew and Wim Lavrijsen)</li>
341          <li class="bug">The setup scripts for Windows now use %TEMP% instead of %HOMEDRIVE%%HOMEPATH% to store temporary files (contributions from Pere Mato and Florence Ranjard)</li>
342          <li class="new">Add the --public and --private global options for cmt commands, to control whether the use graph traverses or not the private sections:
343<pre>
344&gt; cmt --public ...
345</pre>
346       only sees public uses (default behavior for most commands but not for cmt broadcast and cmt show uses which traverse the private sub graphs)
347<pre>
348&gt; cmt --private ...
349</pre>   
350       forces the traversal of private subgraphs. This is already the default behavior for cmt show uses and for cmt broadcast, but can now be applied to any CMT command.</li>
