Asterisk scripting language coding guidelines

Hi. I am developing a set of IVRs for data collection using an Asterisk-based PBX, and I’d like to know if anyone has developed a list of coding guidelines for the Asterisk scripting language. I found a list of coding guidelines for contributing to the Asterisk C source at , but I am instead looking for guidelines on developing code in the Asterisk scripting language used in dialplans, such as extensions.conf.

I’d appreciate any resources you could point me to. Thanks,
