This page is an attempt to collect a list of the different parts of EPICS V4 and eventually to identify where and how they will interface to one another and to the outside world. There will probably be many omissions from my initial versions of this list, so please contribute.


Modules

Infrastructure

Other Tools

Interfaces

Not quite sure how to structure this section yet; an interface is implemented by one or more modules and called by other modules for communication or control purposes.
