+\r
+This needs to be relative to ${dir}, not ${srcdir} in order not to break\r
+out of tree builds. You can test with\r
+\r
+% mkdir -p /tmp/foo-build\r
+% cd /tmp/foo-build\r
+% ~/projects/notmuch/configure && make\r
+\r
+Also, one Makefile gotcha is that anything using $(dir) should use :=\r
+rather than = to force immediate expansion.\r
+\r
