Click //Finish//. (Eclipse might ask you whether you want to switch to the //Plug-in Development Perspective//, which configures Eclipse to provide the views that are important for plug-in development. Choose //Yes//. Or //No//. It won't have a big influence on your future...)
66	66	1. Eclipse has now created your new plug-in and was nice enough to open the //Plug-in Manifest Editor//, which allows you to graphically edit two important files of your plugin: {{code language="none"}}plugin.xml{{/code}} and {{code language="none"}}META-INF/MANIFEST.MF{{/code}}. (By the way, this would be a great time to research the editor and the two files online.) Basically, those two files provide information that tell Eclipse what other plug-ins your plug-in needs and how it works together with other plug-ins by providing extensions and extension points. Our new plug-in will depend on two other plug-ins, so switch to the //Dependencies// tab of the editor and add dependencies to {{code language="none"}}org.eclipse.ui.editors{{/code}} and {{code language="none"}}org.eclipse.jface.text{{/code}}. Save the editor and close it. (You can always reopen it by opening one of the two mentioned files from the //Package Explorer//.)

	70	+We will now create the class that implements the simple text editor. There won't be any programming involved here since we're lazy; instead, we will just inherit from an existing simple text editor.

	75	+== Register the Editor ==

	77	+For the editor to be available inside Eclipse, we will have to register it by adding an extension to an extension point.

	79	+1. Copy [[the attached file>>attach:turing-file.gif]] to a new subfolder icons in the plug-in folder (right-click the plug-in folder in the //Package Explorer// and choose //New// -> //Folder...//). You can copy the file by importing it from inside Eclipse (//File// -> //Import...// -> //File System//) or by copying it from outside Eclipse and refreshing the plug-in project afterwards (right-click the plug-in folder in the //Package Explorer// and choose //Refresh).//
	80	+1. Open the //Plug-in Manifest Editor// again and switch to the //Extensions// tab.
	81	+1. Click //Add...//, choose the {{code language="none"}}org.eclipse.ui.editors{{/code}} extension point and click //Finish//.
	82	+1. The extension point is now shown in the list of extensions, along with an //editor// extension. Select that extension and edit its details using the fields on the right. Set the ID to {{code language="none"}}de.cau.cs.rtprakt.login.simple.editor{{/code}}, the name to {{code language="none"}}Simple Text Editor{{/code}}, the icon to {{code language="none"}}icons/turing-file.gif{{/code}}, the extensions to {{code language="none"}}simple{{/code}}, the class to {{code language="none"}}de.cau.cs.rtprakt.login.simple.editors.SimpleEditorPart{{/code}}, and the default to {{code language="none"}}true{{/code}}.
	83	+1. Save and close the manifest editor.
