00023 //       Class : WordWrapStream
00024 // Description : A special ostream that formats all of its output
00025 //               through ProgramBase::show_text().  This allows the
00026 //               program to easily word-wrap its output messages to
00027 //               fit the terminal width.
00028 //
00029 //               By convention (inherited from show_text), a newline
00030 //               written to the WordWrapStream indicates a paragraph
00031 //               break, and is generally printed as a blank line.  To
00032 //               force a line break without a paragraph break, use
00033 //               '\r'.
