 In order to keep the code nice and clean we have a few requirements you'll
 need to stick to in order to get your patch accepted:
 
-- use 8-space tabs for indentation
+- use 2-space no-tabs for indentation (mandatory on new files, old ones will
+  be re-indented eventually. When modifying an existing file with 8-space
+  indentation keep the old style please)
 - curly brackets are on a new line
 - please compare with NULL or FALSE isntead of using "!"
 - callback functions have a suffix _cb
