how to include 3rd party script to my script?

[bobas]

Hello
I want make boxplot. Suprisingly, it is not part of Scilab, but made by 
user. I found that script in:
http://www.scilab.org/contrib/index_contrib.php?page=displayContribution&fileID=1089

I want use this script to create box plot. But I don't known how include 
it to my scripts. Another way is add this script to the Scilab, but I 
don't known how to do it.

For example my script is as follow:

// here I want include boxplot.sci

lProbe1 = rand(100, 1, "normal");
boxplot(lProbe1);


How make this script workable???


thanks
