  13     wxFileConfig implements wxConfigBase interface for
  14     storing and retrieving configuration information using plain text files. The
  15     files have a simple format reminiscent of Windows INI files with lines of the
  16     form @c "key = value" defining the keys and lines of special form
  17     @c "[group]" indicating the start of each group.
  18
  19     This class is used by default for wxConfig on Unix platforms but may also be
  20     used explicitly if you want to use files and not the registry even under
  21     Windows.

  67         after saving it successfully, the dirty flag is reset so no changes will be
  68         written back to the file this object is associated with until you change its
