Thanks for the tip Chris, been away from the newsgroups for a while and 
bad habits seem to have crept in.  All in all, a none-to-useful first 
post to comp.lang.python, here's hoping for a brighter future.

Can I presume the lack of a solution in your response means, 
essentially, prior to 2.6 there's no way of reading from the script that 
the interpreter has been launched in interactive mode?
