You will be typing a lot of repetitive lines. A simple for(n..q) construct can save you a lot of time. XML will require you to write many, many lines that look 99% the same ... <key> filenames </key> <array> <string> 00.gif</string> <string> 01.gif</string> ... <string> _n_.gif</string> </array> The ability to have something spit out that n-many lines is very handy. BTW. I’m re-adding all the other pages previously known in the previous incarnation of the site. Please tolerate some ugly pages.
