It does this by working with the server to keep track of when it is +activated and stores information on how to reactivate it. Method +invocations on the server will actually be sent to the Implementation +Repository, which will then be able to start the server process if it is not +already running and forward the invocation to the real server. </p> + +<p>In the pages here (and in most of the documentation written for it), +Implementation Repository will often be shortened to ImplRepo or IR.</p> <hr> -<h3>Other IR Documents</h3> - -<dl> - <dt><img - src="http://www.cs.wustl.edu/~schmidt/gifs/misc/redball.gif" - alt="o" width="14" height="14"> <a href="status.html">Status - Page</a> - This page details a checklist of short-term - and long-term goals for the development of the IR. </dt> - <dd> </dd> - <dt><img - src="http://www.cs.wustl.edu/~schmidt/gifs/misc/redball.gif" - alt="o" width="14" height="14"> <a href="usersguide.html">Users - Guide</a> - Overall documentation on how to use the IR in - your programs. </dt> - <dd> </dd> - <dt><img - src="http://www.cs.wustl.edu/~schmidt/gifs/misc/redball.gif" - alt="o" width="14" height="14"> <a href="paper.html">The - Paper</a> - A paper that has a general description of the - IR.
