   1 // A TParser is a class for parsing input and formatting it (presumabyl for
   2 // display on the screen).  All parsers are derived from the TParser class,
   3 // in order to facilitate extending telnet to include other kinds of
   4 // output.  Currently, only one parser is implemented, the ANSI parser.
   5 // A TParser includes:
   6 //   - A ParseBuffer function, which takes as parameters start and end
   7 //     pointers.  It returns a pointer to the last character parsed plus 1.
   8 //     The start pointer is the beginning of the buffer, and the end
   9 //     pointer is one character after the end of the buffer.
  10 //   - An Init() function, which will re-initialize the parser when
  11 //     necessary.
