description         A portable, pure C implementation of the Git core methods
long_description    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 which \
                    supports C bindings.
