  13    Here are brief descriptions of the filename formats supported by this class:
  14
  15    wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file
  16                 names have the form:
  17                 /dir1/dir2/.../dirN/filename, "." and ".." stand for the
  18                 current and parent directory respectively, "~" is parsed as the
  19                 user HOME and "~username" as the HOME of that user
  20
  21    wxPATH_DOS:  DOS/Windows format, absolute file names have the form:
  22                 drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
  23                 letter. "." and ".." as for Unix but no "~".
  24
  25                 There are also UNC names of the form \\share\fullpath
  26
  27    wxPATH_MAC:  Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file
  28                 names have the form
  29                     volume:dir1:...:dirN:filename
  30                 and the relative file names are either
  31                     :dir1:...:dirN:filename
  32                 or just
  33                     filename
  34                 (although :filename works as well).
  35                 Since the volume is just part of the file path, it is not
  36                 treated like a separate entity as it is done under DOS and
  37                 VMS, it is just treated as another dir.
  38
  39    wxPATH_VMS:  VMS native format, absolute file names have the form
  40                     <device>:[dir1.dir2.dir3]file.txt
  41                 or
  42                     <device>:[000000.dir1.dir2.dir3]file.txt
  43
  44                 the <device> is the physical device (i.e. disk). 000000 is the
  45                 root directory on the device which can be omitted.
  46
  47                 Note that VMS uses different separators unlike Unix:
  48                  : always after the device. If the path does not contain : than
  49                    the default (the device of the current directory) is assumed.
  50                  [ start of directory specyfication
  51                  . separator between directory and subdirectory
  52                  ] between directory and file
