+      There are any number of "resheader" rows that contain simple 
+      name/value pairs.
+      
+      Each data row contains a name, and value. The row also contains a 
+      type or mimetype. Type corresponds to a .NET class that support 
+      text/value conversion through the TypeConverter architecture. 
+      Classes that don't support this are serialized and stored with the 
+      mimetype set.
+      
+      The mimetype is used for serialized objects, and tells the 
+      ResXResourceReader how to depersist the object. This is currently not 
+      extensible. For a given mimetype the value must be set accordingly:
+      
+      Note - application/x-microsoft.net.object.binary.base64 is the format 
+      that the ResXResourceWriter will generate, however the reader can 
+      read any of the formats listed below.

-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.
