+## Set merge driver for ChangeLog files 
+# See gnulib's lib/git-merge-changelog.c (or git-merge-changelog(1))
+# for per-user setup instructions.
+#
+# The short version of this (optional) procedure is:
+# 
+# (1) Install git-merge-changelog (this is the tricky part!)
+#
+# (2) Add something like the following to your ~/.gitconfig:
+#
+# [merge "merge-changelog"]
+#         name = GNU-style ChangeLog merge driver
+#         driver = git-merge-changelog %O %A %B
+#
+# (3) Enjoy mostly effortless ChangeLog merges, at least until the
+#     file gets renamed again ...
