Trace2 config settings are only read from the system and global
config files; repository local and worktree config files and `-c`
command line arguments are not respected.

trace2.normalTarget::
	This variable controls the normal target destination.
	It may be overridden by the `GIT_TRACE2` environment variable.
	The following table shows possible values.

trace2.perfTarget::
	This variable controls the performance target destination.
	It may be overridden by the `GIT_TRACE2_PERF` environment variable.
	The following table shows possible values.

trace2.eventTarget::
	This variable controls the event target destination.
	It may be overridden by the `GIT_TRACE2_EVENT` environment variable.
	The following table shows possible values.

trace2.normalBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from normal output.  May be overridden by the
	`GIT_TRACE2_BRIEF` environment variable.  Defaults to false.

trace2.perfBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from PERF output.  May be overridden by the
	`GIT_TRACE2_PERF_BRIEF` environment variable.  Defaults to false.

trace2.eventBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from event output.  May be overridden by the
	`GIT_TRACE2_EVENT_BRIEF` environment variable.  Defaults to false.

trace2.eventNesting::
	Integer.  Specifies desired depth of nested regions in the
	event output.  Regions deeper than this value will be
	omitted.  May be overridden by the `GIT_TRACE2_EVENT_NESTING`
	environment variable.  Defaults to 2.

trace2.configParams::
	A comma-separated list of patterns of "important" config
	settings that should be recorded in the trace2 output.
	For example, `core.*,remote.*.url` would cause the trace2
	output to contain events listing each configured remote.
	May be overridden by the `GIT_TRACE2_CONFIG_PARAMS` environment
	variable.  Unset by default.

trace2.destinationDebug::
	Boolean.  When true Git will print error messages when a
	trace target destination cannot be opened for writing.
	By default, these errors are suppressed and tracing is
	silently disabled.  May be overridden by the
	`GIT_TRACE2_DST_DEBUG` environment variable.

trace2.maxFiles::
	Integer.  When writing trace files to a target directory, do not
	write additional traces if we would exceed this many files. Instead,
	write a sentinel file that will block further tracing to this
	directory. Defaults to 0, which disables this check.
