EVE is a small execution engine that was designed to be placed at any level of winIDEA software and execute short programs of calls to available (i.e. registered) callbacks at a certain level. EVE scripts' use cases differ from Python scripts which are used for the high-level control of winIDEA and configuration setup.
These scripts are written in C (C++) and can be called from several points in time, e.g. start of the debug session, and the start of the trace via iSYSTEM.iConnect service call.
