5.6 Trace variables

max-trace-indent	The maximum indentation used during output from trace.
trace-indent-width
	The additional amount by which tracing output is indented upon entering a deeper level of nesting.
trace-level	The current depth of tracing.
cl:trace-output	The stream to which tracing sends its output by default.
traced-arglist	The variable that holds the arguments given to the traced function.
traced-results	The variable that holds the results from the traced function.

The following four variables allow you to control the style of tracing output separately from normal printing:

trace-print-circle
	The value to which print-circle is bound during output from trace.
trace-print-length
	The value to which print-length is bound during output from trace.
trace-print-level
	The value to which print-level is bound during output from trace.
trace-print-pretty
	The value to which print-pretty is bound during output from trace.

trace-print-circle
	The value to which print-circle is bound during output from trace.
trace-print-length
	The value to which print-length is bound during output from trace.
trace-print-level
	The value to which print-level is bound during output from trace.
trace-print-pretty
	The value to which print-pretty is bound during output from trace.
