"""
This abstract class ApiFcts defines the interface for the execution of any command-line-functions.
It uses the following configuration
  .a) COMP.conf->artifact->api->[system] : for structural attributes of the operating-system \n
  .c) COMP.conf->conn->[api] : for connection-attributes and structural attributes,
  maybe specialized for the operating-system

The attribute type resolves which technique is used, implemented in a specific tool-class:

The main tasks are: \n
