+# DESCRIPTION: This file is invoked two times. first time from Makefile with
+#              PASS == 1 and second time in Dockerfile.in with PASS == 2. In
+#              dockcross container, the current libstdc++ is not the same as
+#              in manylinux containers. So, copying the libstdc++ form manylinux
+#              container to dockcross container. It is being done int 2 pass.
+#              during PASS == 1, the script will copy libstdc++ from manylinux
+#              container to build machine and then during PASS == 2, libstdc++
+#              will be copied from build machine to dockcross container
