thanks for the various advice. I must admit I was concerned with using 
"do". I was thinking about using it for config file slurping but was 
wondering what would happen if some malicious/ignorant user had write 
access to the config file... presumably they could execute any perl code 
they wanted as the userid that the main script is running as?

As for taking the code out of the 3rd party perl script - I am loathe to 
do this as the script is in active development and I would have to 
deconstruct new versions as they were published creating lots of work 
for something that is supposed to save me lots of work!

So far, using pipes looks the best option.

ps this particular project is the first time I'm using perl to produce 
html so I will probably have questions about that soon too!
