I just took over maintaining a web site and the previous caretaker was
using "spamstopper" 
http://www.apple.com/downloads/macosx/email_chat/spamstopper.html
an apple program to obfuscate email addresses in html pages so that
spambots wouldn't grab the addresses and go to town.

The site is hosted on Linux an I'd like to find something I can run
there from the command line or maybe even better would be to use some
php?  I don't know as I'm pretty new to the email obfuscation scene :)

any recommendations?
