  /*
     Here are brief descriptions of the filename formats supported by this class:
  
     wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file
                  names have the form:
                  /dir1/dir2/.../dirN/filename, "." and ".." stand for the
                  current and parent directory respectively, "~" is parsed as the
                  user HOME and "~username" as the HOME of that user
  
     wxPATH_DOS:  DOS/Windows format, absolute file names have the form:
                  drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
                  letter. "." and ".." as for Unix but no "~".
  
                  There are also UNC names of the form \\share\fullpath
  
     wxPATH_MAC:  Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file
                  names have the form
                      volume:dir1:...:dirN:filename
                  and the relative file names are either
                      :dir1:...:dirN:filename
                  or just
                      filename
                  (although :filename works as well).
                  Since the volume is just part of the file path, it is not
                  treated like a separate entity as it is done under DOS and
                  VMS, it is just treated as another dir.
  
     wxPATH_VMS:  VMS native format, absolute file names have the form
                      <device>:[dir1.dir2.dir3]file.txt
                  or
                      <device>:[000000.dir1.dir2.dir3]file.txt
  
                  the <device> is the physical device (i.e. disk). 000000 is the
                  root directory on the device which can be omitted.
  
                  Note that VMS uses different separators unlike Unix:
                   : always after the device. If the path does not contain : than
                     the default (the device of the current directory) is assumed.
                   [ start of directory specyfication
                   . separator between directory and subdirectory
                   ] between directory and file
