Format text e-mail using Petal
PetalMail processes a Petal XML template, and then turns the resulting XML into a text email which can be sent through sendmail or other. The XML has to follow a certain syntax which is defined in this documentation.
Since PetalMail’s is a subclass of Petal, its API is the same. Which means you need to read about Petal before you can use PetalMail.
