Common Text Transformation Library: line

Demonstrates text line parser which uses asymmetric quote, quote(true,RM,RR), to parse individual lines inside user input.

// sample code: line_parser.cpp
// demonstrates text line parser that uses quote( true, middle_expr, right_expr )

//#define CTTL_TRACE_EVERYTHING //define to turn tracing on
//#define CTTL_TRACE_RULES  //define to turn light tracing on
