 		<title>Introduction</title>
 		<para>The extensions system in Inkscape is a way for adding functionality to Inkscape, without affecting the core of the program itself.  We want Inkscape to follow a core-plus-modules approach similar to that adopted by many successful open source projects such as the Linux kernel, Perl, Apache, Gimp, and so on.  There are many different types of extension mechanisms, including file format conversion tools, filter scripts that process SVG, user interface elements that can be added at runtime, and so forth.</para>
 		<para>This proposal defines a design for handling this wide variety of extensions in a flexible manner.  This document provides a way to understand the extensions system, and how extensions fit into this overall system.</para>
-		<para>Much of the documentation that will be useful for users of the extension system is not included in this document, it is autogenerated from the source code and placed on the Inkscape webpage.  While this is less convienient, it is more correct, and maintained as the source code is modified.  Please look aton the Inkscape webpage also.</para>

This includes information on the type of file the input module can take in including its filename extension and mime type.  Also, there is a space to store a tooltip for additional information on the file type in the file dialog.  Lastly, there is the key of which Output extension is recommended for saving this filetype.  This is useful, as there is no other direct links between the Input and Ouput functions, and a user expects to be able to open and save without using the 'Save As...' dialog.</para>
