+== Motivation
+Print as much information about the build process as you can get from within the binary.
+Espacially, compiler flags - they are quite important when comparing performance.
+The information should be included in the binary, so it can't be lost and is right next to, for example, a benchmark result.
+So there's no chance to mix up different flags.
+
+== Other options
+Another option would be -g -grecord-gcc-switches and search for DW_AT_producer.
+Sadly, this doesn't produce the wanted information with clang:
+  * clang++: DW_AT_producer    : (indirect string, offset: 0x0): clang version 3.9.1 (tags/RELEASE_391/final)
+  * g++: DW_AT_producer    : (indirect string, offset: 0x37): GNU C++ 4.9.4 -mtune=generic -march=x86-64 -g -O3 -frecord-gcc-switches -fstack-protector-strong
+
+Passing the CPPFLAGS and so on as -DMY_FLAGS=.... to the compiler call will not include some information set by the compiler itself (compare the parameters set in the Makefile with the printed output).
+
+== Known limitations
+* Works only with GCC for now.
