- * This file was at one time responsible for doing all deliveries, but this caused
- * big problems on shared hosting systems, where the process might get killed by the 
- * hosting provider and nothing would get delivered. 
- * It now only delivers one message under certain cases, and invokes a queued
- * delivery mechanism (include/deliver.php) to deliver individual contacts at 
- * controlled intervals.
- * This has a much better chance of surviving random processes getting killed
- * by the hosting provider. 
- *
- * The basic flow is:
- *   Identify the type of message
- *   Collect any information that needs to be sent
- *   Convert it into a suitable generic format for sending
- *   Figure out who the recipients are and if we need to relay 
- *       through a conversation owner
- *   Once we know what recipients are involved, collect a list of 
- *       destination sites
- *   Build and store a queue item for each unique site and invoke
- *       a delivery process for each site or a small number of sites (1-3)
- *       and add a slight delay between each delivery invocation if desired (usually)
- *
