DfmToLfm now supports converting a Lazarus form file too, as a way
+to create more than one version of the same form, for example to conditionally
+include a different version based on widgetset target. For example, you could
+do this in a form's unit:
+
+{$IFNDEF LCLCarbon}
+ {$R *.lfm} //include generic form with Windows and Linux
+{$ELSE}
+ {$R *.mac.lfm} //include prettied form with Mac (-m -s switches)
+{$ENDIF}
