23 // The Abseil Logging library supports the following command line flags to
24 // configure logging behavior at runtime:
25 //
26 // --stderrthreshold=<value>
27 // Log messages at or above this threshold level are copied to stderr.
28 //
29 // --minloglevel=<value>
30 // Messages logged at a lower level than this are discarded and don't actually
31 // get logged anywhere.
32 //
33 // --log_backtrace_at=<file:linenum>
34 // Emit a backtrace (stack trace) when logging at file:linenum.
35 //
36 // To use these commandline flags, the //absl/log:flags library must be
37 // explicitly linked, and absl::ParseCommandLine() must be called before the
38 // call to absl::InitializeLog().
39 //
40 // To configure the Log library programmatically, use the interfaces defined in
41 // absl/log/globals.h.
