Alsvid's Julia code is tested with Version 1.7 from https://julialang.org/

Code that was previously developmental has been more thoroughly tested and will
included in Alsvid 6.0 and later versions as part of Alsvid. 

 
The Julia code has a first

#!/usr/local/bin/julia

It will run as an executable similar to how Python command line programs run
under Linux if it is your $PATH and has the executable property.  

Our intent is that you would execute also Julia on the command line or 
in a separate script this way:

julia program.jl command line options

where "julia" is the default version you have at the top of your $PATH.

The Bash script change_julia.sh will replace our first line with one of your
chosing.
