+"""Generate event interfaces .in file (EventInterfaces.in). |
+ |
+The event interfaces .in file contains a list of all Event interfaces, i.e., |
+all interfaces that inherit from Event, including Event itself, |
+together with certain extended attributes. |
+ |
+Paths are in POSIX format, and relative to Source/. |
+ |
+This list is used in core/ to generate EventFactory and EventNames. |
+The .in format is documented in build/scripts/in_file.py. |
