In some cases the license-identification header was missing, so I added that as well. Replaced the remaining headers that specifically identified "Versions 3.13.7 and higher". Makefiles and the build system were deliberately excluded.

|
|
* This library provides a simple global flag facility that can be used to
|
|
* synchronize e.g. plugins with IOC-wide states, that may be derived from
|
|
* events (either soft events or hard events coming from specialized timing
|
|
* and event hardware).
|
|
*
|
|
* A subset of this API is provided as IOC Shell commands to allow
|
|
* command line debugging.
