@ -15,8 +15,6 @@ We have the following conventions in our code:
* 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.
