		<h2>Overview</h2>
		<p>
		The Linux Distributions OProfile plugin aims to bring the powerful call profiling
		capabilities of OProfile to Eclipse, in a manner that is easy to use for developers
		of any level of experience. Inexperienced users can, with 1 click, determine the parts
		of their code which use the most time while experienced users of OProfile can perform
		the same functions they would on the command-line but with a much more rich visualization
		of the results.
		</p>

		<h2>Current Status</h2>
		<p>
		In conjunction with CDT 5.0, the plugin can do the following:
		<ul>
          <li>Launch a local C/C++ application and OProfile simultaneously to start profiling (requires root password to execute OProfile commands)</li>
          <li>Automatically gather OProfile data and display in a tree viewer after a launch</li>
          <li>Configure OProfile to profile several events simultaneously with as many debug registers as the CPU/OProfile supports</li>
          <li>Configure OProfile to profile relevant shared-libraries and/or kernel modules</li>
          <li>Jump to the line-number of the corresponding source file on a double-click of a sample</li>
          <li>Prompt to save the default session on double-click</li>
          <li>View the oprofiled log</li>
          <li>One-click launch with sane defaults</li>
        </ul>
		</p>

		<h2>Future Plans</h2>
		<p>
		<ul>
		  <li> Robust filtering for events/sessions/images</li>
		  <li> Code-colourization (similar to <a href="http://www.eclemma.org/index.html" class="external text" title="http://www.eclemma.org/index.html" rel="nofollow">EclEmma</a>) for code hotspots</li>
          <li> Comparing two sessions/runs similar to functionality of opreport</li>
          <li> Increase test coverage</li>
        </ul>
		</p>

		<h2>Try it out</h2>
		<p>
		  At present we have no update site, but you can check the project plugins out of SVN
		  directly from eclipse.org at svn://dev.eclipse.org/svnroot/technology/org.eclipse.linuxtools.
          You will need the 5 plugins under oprofile/trunk, and the 2 plugins under profiling/trunk:
<pre>     
	org.eclipse.linuxtools.oprofile.core
	org.eclipse.linuxtools.oprofile.core.linux.x86
	org.eclipse.linuxtools.oprofile.core.linux.x86_64
	org.eclipse.linuxtools.oprofile.launch
	org.eclipse.linuxtools.oprofile.ui
	org.eclipse.linuxtools.profiling.launch
	org.eclipse.linuxtools.profiling.ui
</pre>
		To install, run (as root) the script in org.eclipse.linuxtools.oprofile.core/natives/linux/scripts (currently only works on Fedora machines). This will ensure all the necessary programs are installed and create a wrapper for opcontrol to allow root authentication with the root password:
<pre>
	$ sudo ./install
</pre>

From there, run the plugin as an Eclipse Application.  So far, we have tested using Eclipse 3.4.1, CDT 5.0, OProfile 0.9.3 on Fedora 9 x86 and Fedora 10 x86_64.
