 libgit2 - the Git linkable library
-==================================
+======================
 
 libgit2 is a portable, pure C implementation of the Git core methods provided as a
 re-entrant linkable library with a solid API, allowing you to write native
 speed custom Git applications in any language with bindings.
 
 Why Do We Need It
-==================================
+=======================
 
 In the current Git project, though a libgit.a file is produced it is
 not re-entrant (it will call <code>die()</code> on basically any error)
