Change your code.  It'll be easier to do it now than to unpick 
everything later.

What you want (probably) is to wrap your code in the require'd file into 
a class that you can instantiate with the relevant parameters in your 
main script.

It's a heredoc marker.  It's just another way of creating a multiline 
string.  The critical bit is the "<<EOS" start marker - after "<<" you 
can put any identifier, and a string will be created from the content 
between that line and the first occurrence of that marker on its own 
later in the file.
