Subject: Re: CGI question

Hey Assaf,

In a real server case it would send parameters to the script.
In a command line case once the cgi code scope ended it will require the 
parameters entered one by one and CTRL+D should run it.

I am using ruby for CGI scripts but formatting a form this way can be 
very painful.
I would go for writing the RAW html by myself with touches of variables 
if needed.

Regards,
Eliezer
