<h3>Description.</h3>
<dl>
<dt><b>oop_tcl_new</b>
<dd>Create a liboop source which uses the
<a href="http://www.purl.org/tcl/home/man/tcl8.3.2/TclLib/DoOneEvent.htm">Tcl
event loop</a> for events. There is only one such event loop, so this
function is global. You may call it multiple times; it will return the same
event source, but keep count of the number of users.<p>
Events will be dispatched when the Tcl event loop is run, either directly
via Tcl_DoOneEvent() or indirectly via Tk_MainLoop(). Unfortunately, there
is no way to stop the Tcl event loop, so return values from event handlers
are ignored.<p>
<dt><b>oop_tcl_delete</b>
<dd>Delete the liboop source created with oop_tcl_new(). This decrements the
count of users; when oop_tcl_delete has been called as many times as
oop_tcl_new, the event source is removed.<p>
