Rule File (Using a Proxy server)

I am puzzled,  I have read through the manual for the Library and the ComLine 
'browser' and have seen many references to rule files. Does anybody have a
sample rule file?  Or know where I can find one?

I hope to use the rule file to et ComLine to use a proxy server.  If a rule
file is not the appropriate way to do this, are there any suggestions about
a better way to do this?
