+// go-git aims to reach the completeness of libgit2 or jgit, nowadays covers the
+// majority of the plumbing read operations and some of the main write

+// It is highly extensible, we have been following the open/close principle in
+// its design to facilitate extensions, mainly focusing the efforts on the
