+//    First checked in on 98/11/20 by John R. McMullen in the wrong directory.
+//    Checked in again 98/12/04.
+//    Polished version 98/12/08.
+//    Completely rewritten to integrate with nsIInputStream and nsIOutputStream (the
+//        xpcom stream objects.
+
+//========================================================================================
+//
+//  Classes defined:
+//
+//          nsInputStream, nsOutputStream
+//                These are the lightweight STATICALLY LINKED wrappers for
+//                the xpcom objects nsIInputStream and nsIOutputstream.
+//             Possible uses:
+//                If you are implementing a function that accepts one of these xpcom
+//                streams, just make one of these little jobbies on the stack, and
+//                the handy << or >> notation can be yours.
+//                
+//          nsInputFileStream, nsOutputFileStream
+//                These are the STATICALLY LINKED wrappers for the file-related
+//                versions of the above.
+//          nsIOFileStream
+//                An input and output file stream attached to the same file.
+//
+//  This suite provide the following services:
+//
+//      1.  Encapsulates all platform-specific file details, so that file i/o
+//          can be done correctly without any platform #ifdefs
+//
+//      2.  Uses NSPR file services (NOT ansi file I/O), in order to get best
+//          native performance.  This performance difference is especially large on
+//          macintosh.
+//
+//      3.  Allows all the power of the ansi stream syntax.
+//
+//          Basic example:
+//
+//              nsFileSpec myPath("/Development/iotest.txt");
+//
+//	            nsOutputFileStream testStream(myPath);
+//				testStream << "Hello World" << nsEndl;
+//
+//      4.  Requires streams to be constructed using typesafe nsFileSpec specifier
+//          (not the notorious and bug prone const char*), namely nsFileSpec.  See
+//          nsFileSpec.h for more details.
+//
+//      5.  Fixes a bug that have been there for a long time, and
+//          is inevitable if you use NSPR alone:
+//
+//               The problem on platforms (Macintosh) in which a path does not fully
+//               specify a file, because two volumes can have the same name.
+//
+//  Not yet provided:
+//
+//      Endian-awareness for reading and writing crossplatform binary files.  At this
+//      time there seems to be no demand for this.
