## Style Guide
`libgit2` is written in [ANSI C](http://en.wikipedia.org/wiki/ANSI_C)
(a.k.a. C89) with some specific conventions for function and type naming,
code formatting, and testing.
The public API of `libgit2` is [ANSI C](http://en.wikipedia.org/wiki/ANSI_C)
(a.k.a. C89) compatible. Internally, `libgit2` is written using a portable
subset of C99 - in order to compile with GCC, Clang, MSVC, etc., we keep
local variable declarations at the tops of blocks only and avoid `//` style
