+// On GNU/Linux, you have few choices to get the most out of your stack trace.
+//
+// By default you get:
+//	- object filename
+//	- function name
+//
+// In order to add:
+//	- source filename
+//	- line and column numbers
+//	- source code snippet (assuming the file is accessible)
+
+// Install one of the following libraries then uncomment one of the macro (or
+// better, add the detection of the lib and the macro definition in your build
+// system)
+
+// - apt-get install libdw-dev ...
+// - g++/clang++ -ldw ...
+// #define BACKWARD_HAS_DW 1
+
+// - apt-get install binutils-dev ...
+// - g++/clang++ -lbfd ...
+// #define BACKWARD_HAS_BFD 1
+
+// - apt-get install libdwarf-dev ...
+// - g++/clang++ -ldwarf ...
+// #define BACKWARD_HAS_DWARF 1
+
+// Regardless of the library you choose to read the debug information,
+// for potentially more detailed stack traces you can use libunwind
+// - apt-get install libunwind-dev
+// - g++/clang++ -lunwind
