bmx is simple shell script to run mx in batch and prompt you when it is 
complete.  

To install:
cp bmx /usr/local/bin (assuming that this is where you keep such things)

You will need to edit the path to mx if you keep the mx binary elsewhere 
than in /usr/local/bin

To use:
bmx file

where file.mx is your input file name.  It will create the output 
file file.mxo in the same directory.
