Subject: Conditionals in the buildsystem language allowing for checking of
 configure flags: /* $If: USE_KQUEUE */ /* $ExtraSources:
 socketengine_kqueue.cpp */ /* $ExtraObjects: socketengine_kqueue.o */ /*
 $EndIf */ This is used exactly where the example dictates: to pick a socket
 engine from the socketengine.cpp.
