+#!/usr/bin/env sh
+#
+# This is a simple script which attempts to convert ser modules so that they
+# can be used with the sip-router core. Most of the changes done by the script
+# deal with the changes in the database abstraction layer in the sip-router
+# source tree.
+#
+# Run this script in module directory to convert it from ser core to
+# sip-router core. The root of the tree should be two levels up, otherwise
+# relative paths to headers (../..) would not work and the module will not
+# compile.
+# 
+# Some of the changes done by the script:
+#
+#  * Extra defines in the Makefile to make the module link with libsrdb2
+#  * Path to database headers updated to point to lib/srdb2
+#  * Database flag names renamed from DB_* to SRDB_* 
+#    (DB_DISABLED -> SRDB_DISABLED)
+#
+# NOTE: There is no guarantee that the update module would compile or even
+#       work. Make a backup before running the script. You have been warned!
