Most files use the Kernighan & Ritchie coding style with 2 spaces of
indentation. The indent program can help you to stick to it:
-indent -kr -br -brs -ce -bbo --dont-break-procedure-type --no-tabs
---cuddle-do-while --cuddle-else --indent-level2 --leave-preprocessor-space
---no-space-after-function-call-names <myfile>
+indent -kr -l80 -nut -i2 -lps -npcs -br -brs -ce -cdw -bbo -npsl <myfile>
+
+The script ./tools/indent runs indent with the appropriate options.
FIXME: this list of arguments is still to be discussed, maybe
