72 The call structure of the functions is represented using
73 indentation and vertical lines. Extra information is printed using
74 horizontal lines that connect to the vertical line.
75
76 The return value is represented using the arrow "->>". For simple
77 functions, the arrow can be printed on the same line as the
78 function name. If more output is printed, it is connected to the
79 vertical line of the function.
80
81 The first column contains the file name, the second the line
82 number, and the third a number increasing for each trace line.

84 Note, when trace output from several threads are mixed, the output
85 can become misaligned, as all threads (currently) share one state.
86 This is post prominent when the EVENTS part is enabled.
