3
+# An example hook script to verify if you are on battery, in case you
4
+# are running Linux. Called by git-gc --auto with no arguments. The hook
5
+# should exit with non-zero status after issuing an appropriate message
6
+# if it wants to stop the auto repacking.
7
+#
8
+# This hook is stored in the contrib/hooks directory. Your distribution
9
+# may have put this somewhere else. If you want to use this hook, you
10
+# should make this script executable then link to it in the repository
11
+# you would like to use it in.
12
+#
13
+# For example, if the hook is stored in
14
+# /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
15
+#
16
+# chmod a+x pre-auto-gc-battery
17
+# cd /path/to/your/repository.git
18
+# ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
