Before using the example programs:

The libblxsocket.so shared library should be copied to your /usr/lib directory. Normally this
copy will require elevated privileges, so your copy command will look like:

> sudo cp <location of the library> /usr/lib

-------------
To run the BLXEthTest command line example program:
> ./BLXEthTest -?

will print the help message.

> ./BLXEthTest -d 192.168.100.10

will display information from the BLX device

Note that the BLXEthTest command line program interprets the command line as one complete
action, it does not interpret individual command line options in sequence like the python example
command line program.

-------------
The command line example program is intended to show you how you can use the BLX socket library
from your own application software, and provide simple examples of a command line program you can
customize to perform the functions you want.
