00023 //       Class : LineStream
00024 // Description : This is a special ostream that writes to a memory
00025 //               buffer, like ostrstream.  However, its contents can
00026 //               be continuously extracted as a sequence of lines of
00027 //               text.
00028 //
00029 //               Unlike ostrstream, which can only be extracted from
00030 //               once (and then the buffer freezes and it can no
00031 //               longer be written to), the LineStream is not
00032 //               otherwise affected when a line of text is extracted.
00033 //               More text can still be written to it and continuously
00034 //               extracted.
