run.php vs robin.php: which mode do I use?

The engine ships with two main catching scripts:

• run.php — single-domain, non-blocking mode. Use it when you are focusing on one name.
• robin.php — round-robin mode. It reads multiple domains from a flatfile list and runs fully automated, cycling through them.

Both run multi-socket and non-blocking. For catching many names hands-off, put them in the flatfile list and run robin.php; for a single targeted catch, use run.php. Several additional utilities are also provided, along with nightly Nominet droplist downloads to feed your lists.
