+# Beautify the code.
+# Note that this works well on C code, but does some odd joining of lines for C++ code.
+# Compiling with -DNDEBUG and no optimisations will allow one to do a binary diff of the
+# swig executable as a way of checking before and after the 'beautifying'.
+# Single files can be beautified with the beautify-file target, eg: 'make beautify-file INDENTFILE=chosenfile.c'
