+# Rewrite a strings file to get rid of line break/whitespace combinations that get stripped when building with Gradle.
+#
+# Example:
+#   <string name="account_size_changed">
+#   Account \"<xliff:g id="account">%s</xliff:g>\" shrunk from
+#   <xliff:g id="oldSize">%s</xliff:g>
+#   to
+#   <xliff:g id="newSize">%s</xliff:g>
+#   </string>
+#
+# will be rendered as
+#
+#   Account "account" shrunk from10MB to1MB
+#
+# when built with Gradle, but displays fine when built with Ant.
