arguments to the main function throught runhugs

[thiagohb]

Hello,
I'm a student in Ouro Preto's University (Brazil) and I have a problem:
How can I pass arguments to the main function throught runhugs?
I'll need to use a string in the main function. How can I catch the string 
from command line? 

For example:
runhugs main.hsx test 

Thank you.
