+//    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.
+
+//========================================================================================
+//
+//  Classes defined:
+//
+//      nsFilePath, nsFileURL, nsFileSpec, nsPersistentFileDescriptor
+//      nsDirectoryIterator.
+//
+//  Q.  How should I represent files at run time?
+//  A.  Use nsFileSpec.  Using char* will lose information on some platforms.
+//
+//  Q.  Then what are nsFilePath and nsFileURL for?
+//  A.  Only when you need a char* parameter for legacy code.
+//
+//  Q.  How should I represent files in a persistent way (eg, in a disk file)?
+//  A.  Use nsPersistentFileDescriptor.  Convert to and from nsFileSpec at run time.
+//
+//  This suite provides the following services:
+//
+//      1.  Encapsulates all platform-specific file details, so that files can be
+//          described correctly without any platform #ifdefs
+//
+//      2.  Type safety.  This will fix the problems that used to occur because people
+//          confused file paths.  They used to use const char*, which could mean three
+//          or four different things.  Bugs were introduced as people coded, right up
+//          to the moment Communicator 4.5 shipped.
+//
+//      3.  Used in conjunction with nsFileStream.h (q.v.), this supports all the power
+//          and readability of the ansi stream syntax.
+//
+//          Basic example:
+//
+//              nsFilePath myPath("/Development/iotest.txt");
+//
+//              nsOutputFileStream testStream(nsFileSpec(myPath));
+//              testStream << "Hello World" << nsEndl;
+//
+//      4.  Handy methods for manipulating file specifiers safely, e.g. MakeUnique(),
+//          SetLeafName(), Exists().
+//
+//      5.  Easy cross-conversion.
+//
+//          Examples:
+//
+//              Initialize a URL from a string
+//
+//                  nsFileURL fileURL("file:///Development/MPW/MPW%20Shell");
+//
+//              Initialize a Unix-style path from a URL
+//
+//                  nsFilePath filePath(fileURL);
+//
+//              Initialize a file spec from a URL
+//
+//                  nsFileSpec fileSpec(fileURL);
+//
+//              Make the spec unique.
+//
+//                  fileSpec.MakeUnique();
+//
+//              Assign the spec to a URL (causing conversion)
+//
+//                  fileURL = fileSpec;
+//
+//              Assign a unix path using a string
+//
+//                  filePath = "/Development/MPW/SysErrs.err";
+//
+//              Assign to a file spec using a unix path (causing conversion).
+//
+//                  fileSpec = filePath;
+//
+//              Make this unique.
+//
+//                  fileSpec.MakeUnique();
+//
+//      6.  Fixes a bug that have been there for a long time, and
+//          is inevitable if you use NSPR alone, where files are described as paths.
+//
+//          The problem affects platforms (Macintosh) in which a path does not fully
+//          specify a file, because two volumes can have the same name.  This
+//          is solved by holding a "private" native file spec inside the
+//          nsFilePath and nsFileURL classes, which is used when appropriate.

+//    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.
