9 Autogenerated python functions to serialize/deserialize binary messages.
10
11 Generated by: ../aisxmlbinmsg2py.py
12
13 Need to then wrap these functions with the outer AIS packet and then
14 convert the whole binary blob to a NMEA string. Those functions are
15 not currently provided in this file.
16
17 serialize: python to ais binary
18 deserialize: ais binary to python
19
20 The generated code uses translators.py, binary.py, and aisstring.py
21 which should be packaged with the resulting files.
