A very simple FileHandler which allows view the formatted contents of simple RTF (Rich Text Format) documents.
It uses a standard Java control for the loading and display of those documents and will thus not support all possible features which might be present in such documents. Because the support of RTF is only very basic, even the presentation of the document will most probably look very different from what native applications will show.
However, if loading a document succeeds, this at least lets one copy the text contents for reuse in some other editor.
