+# This script will recursively search all |FILES| from the current
+# directory and replace all |TYPES| according to the list below.
+
+# NOTE 1:
+# If this script is run from .../system/bt (as it's intended to be),
+# please edit stack/include/bt_types.h next and remove the typedef's
+# near the top and restore the definitions of TRUE and FALSE. These
+# are still used in the vnd_* files and device specific repositories.
+
+# NOTE 2:
+# The list of files to be modified also includes "*.patch", which means
+# this script can be used to help cherry-picking changes from older
+# branches. Follow this workflow outline:
+#  1. git format-patch [-1] <your sha1>
+#  2. Run change_type script on patch[es]
+#  3. git apply / git am
+
+
+# Regular expression matching the file name
+FILES="\.h$|\.c$|\.cpp$|\.cc$|\.patch$"
+
+# Search/replace terms, separated by ":"
