<h2>Description</h2>

<p>This is the widget you will probably use most often when performing text mining. It reads the
input data file (which can be in XML or SGM format) and sends the token with
the data set to the output channel. It maintains a list of most
recently used data files. To open a new data file, "..." button opens
a standard file dialog. To reread the file, just choose it again from
the pulldown menu.</p>
