ASF4 API

1 Advanced Software Framework Version 4 (ASF4) Introduction and Context
This chapter starts with an overview of the features and objectives of ASF4. The context in the larger SW/Tools ecosystem is defined, giving a relation between the ASF4, START, and the IDE. A high-level work-flow overview is presented and documentation resources are described, to give insight into which references to use for what.
