From 7fb39d5f58efd05e982fe148630edc97ded753b6 Mon Sep 17 00:00:00 2001 From: Petr Baudis Date: Mon, 3 Jul 2006 22:48:07 +0200 Subject: [PATCH] Convert git-annotate to use Git.pm Together with the other converted scripts, this is probably still pu material; it appears to work fine for me, though. The speed gain from get_object() is about 10% (I expected more...).
