45# Process a template within a service framework. A service may encompass
46# PRE_PROCESS and POST_PROCESS templates and an ERROR hash which names
47# templates to be substituted for the main template document in case of
48# error. Each service invocation begins by resetting the state of the
49# context object via a call to reset(). The AUTO_RESET option may be set
50# to 0 (default: 1) to bypass this step.
