-           
+
            Finaly, your Activity may need some resources which you can claim
            here too.
-           
+
            The __init__() method is also used to make the distinction between
-           being resumed from the Journal, or starting with a blank document. 
-           
+           being resumed from the Journal, or starting with a blank document.
+
         2. Implement read_file() and write_file()
            Most activities revolve around creating and storing Journal entries.
            For example, Write: You create a document, it is saved to the Journal
            and then later you resume working on the document.
-           
+
            read_file() and write_file() will be called by sugar to tell your
            Activity that it should load or save the document the user is working
            on.
-           
+
         3. Implement our Activity Toolbars.
            The Toolbars are added to your Activity in step 1 (the toolbox), but
            you need to implement them somewhere. Now is a good time.
-           
+
            There are a number of standard Toolbars. The most basic one, the one
            your almost absolutely MUST have is the ActivityToolbar. Without
            this, you're not really making a proper Sugar Activity (which may be
            okay, but you should really stop and think about why not!) You do
-           this with the ActivityToolbox(self) call in step 1. 
-           
+           this with the ActivityToolbox(self) call in step 1.
+
            Usually, you will also need the standard EditToolbar. This is the one
            which has the standard copy and paste buttons. You need to derive
            your own EditToolbar class from sugar.EditToolbar:
                 class EditToolbar(activity.EditToolbar):
                     ...
-                    
+
            See EditToolbar for the methods you should implement in your class.
-           
+
            Finaly, your Activity will very likely need some activity specific
            buttons and options you can create your own toolbars by deriving a
            class from gtk.Toolbar:
                 class MySpecialToolbar(gtk.Toolbar):
                     ...
-
