+// 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)
