+# A script that can communicate with jungo-based routers

+# Tested with Python 2.5 on Linux and Windows

+"""Usage: %s [options] <IP_address> [redboot.bin]
+Valid options:
+\t-h | --help: usage statement

+\t-f | --file: use <filename> to store dump contents
+\t-u | --user: provide username (default admin)
+\t-p | --pass: provide password (default password1)
+\t-P | --proto: set transfer protocol (default tftp)
+\t-s | --server: IP address of tftp server
