CODING

+JOS CODING STANDARDS
+
+It's easier on everyone if all authors working on a shared
+code base are consistent in the way they write their programs.
+We have the following conventions in our code:
+
+* No space after the name of a function in a call
+  For example, printf("hello") not printf ("hello").
+
+* One space after keywords "if", "for", "while", "switch".
+  For example, if (x) not if(x).
+
+* Space before braces.
+  For example, if (x) { not if (x){.
+
+* Function names are all lower-case separated by underscores.
+
+* Beginning-of-line indentation via tabs, not spaces.
+
+* Preprocessor macros are always UPPERCASE.
+  There are a few grandfathered exceptions: assert, panic,
+  static_assert, offsetof.
+
+* Pointer types have spaces: (uint16_t *) not (uint16_t*).
+
+* Multi-word names are lower_case_with_underscores.
+
+* Comments in imported code are usually C /* ... */ comments.
+  Comments in new code are C++ style //.
+
+* In a function definition, the function name starts a new line.
+  Then you can grep -n '^foo' */*.c to find the definition of foo.
+
+* Functions that take no arguments are declared f(void) not f().
+
+The included .dir-locals.el file will automatically set up the basic
+indentation style in Emacs.
