  43 /// To use this class, create an instance of it, then call DumpLdif(), passing
  44 /// the Contact record object to base the work on.  Output will be written
  45 /// to the stream you provide.  ReadLdif() goes in the other direction.
  46 ///
  47 /// To override LDIF attribute mapping, call Map() or Unmap() as appropriate.
  48 ///
  49 /// To get a list of supported Barry::Contact field names, call GetFieldNames().
  50 /// This function returns a pointer to an array of ContactLdif::NameToFunc
  51 /// structures, ending with NameToFunc::name as null.  You can cycle through the
  52 /// array with code like this:
  53 ///
  54 /// <pre>

  56 ///             ...

  62 /// functions, which are called by DumpLdif().
