+\section intro_sec Introduction
+
+FaxMultiPage is a minimal, but well-documented reference
+implementation of a kviewshell plugin that can serve as a starting
+point for implementations.
+
+\section install_sec Usage
+
+When FaxMultiPage and the associated files are installed, the
+kviewshell program can open TIFF-Fax anf G3 fax files, i.e. files of
+mime types image/fax-g3 or image/tiff.
+
+\section content Content
+
+Only the two classes that are absolutely necessary for a working
+plugin are implemented. The only other file that is installed are
+desktop file, which tells kviewshell to use the plugin.
+
+- FaxMultiPage, an implementation of a KMultiPage. In a larger
+application, this class would contain the GUI elements that the plugin
+adds to the GUI of the kviewshell. For viewing FAXes, no special GUI
+elements are required, and this plugin does only the minimal
+initialization required.
+
+- FaxRenderer, an implementation of a DocumentRenderer. This class is
+responsible for document loading and rendering.
+
+- kfaxmultipage.desktop and kfaxmultipage_tiff.desktop are desktop
+entry files that associate the plugin wit image/fax-g3 or image/tiff
+mime-types. Without these files installed, the file dialog in
+kviewshell would not show FAX files, and the command line "kvieshell
+test.g3" would fail with an error dialog "No plugin for image/fax-g3
+files installed".
