+So, you can read {\it text} floats, integers.
+
+The wxTextInputStream correctly reads text files (or streams) in DOS, Macintosh
+and Unix formats and reports a single newline char as a line ending.
 
 Operator >> is overloaded and you can use this class like a standard C++ iostream.
 Note, however, that the arguments are the fixed size types wxUint32, wxInt32 etc
 and on a typical 32-bit computer, none of these match to the "long" type (wxInt32
 is defined as int on 32-bit architectures) so that you cannot use long. To avoid
-problems (here and elsewhere), make use of the wxInt32, wxUint32, etc types.
