+StartMenu.dll shows a custom page that lets the user select a start menu program 
+folder to put shortcuts in.
+
+To show the dialog use the Select function. This function has one required parameter 
+which is the program group default name, and some more optional switches:
+  /autoadd - automatically adds the program name to the selected folder
+  /noicon - doesn't show the icon in the top left corner
+  /text [please select...] - sets the top text to something else than
+                             "Select the Start Menu folder in which..."
+  /lastused [folder] - sets the edit box to a specific value folder.
+                       Use this to make this plug-in remember the last
+                       folder selected by the user
+  /checknoshortcuts text - Shows a check box with the text "text". If
+                           the user checks this box, the return value
+                           will have > as its first character and you
+                           should not create the program group.
+  /rtl - sets the direction of every control on the selection dialog
+         to RTL. This means every text shown on the page will be
+	 justified to the right.
+
+The order of the switches doesn't matter but the required parameter must come after
+all of them. Every switch after the required parameter will be ignored and left
+on the stack.
+
+The function pushes "success", "cancel" or an error to the stack. If there was no
+error and the user didn't press on cancel it will push the selected folder name
+after "success". If the user checked the no shortcuts checkbox the result will be
+prefixed with '>'. The function does not push the full path but only the selected
+sub-folder. It's up to you to decide if to put it in the current user or all
+users start menu.
+
+To set properties of the controls on the page, such as colors and fonts use Init
+and Show instead of Select. Init will push the HWND of the page on the stack,
+or an error string. For example:
+
+StartMenu::Init "Test"
+Pop $0
+IntCmp $0 0 failed
+GetDlgItem $0 $0 1003
+SetCtlColors $0 "" FF0000
+StartMenu::Show
+# continue as with Select here
+failed:
+
+Look at Example.nsi for a full example (without Init and Select).
