-This contains a copy of libevent-1.4.7-stable for use on Linux and Mac
-
-Rather than use libevent's own build system, we just build a Chrome 
-static library using SConscript
-
-Changes from upstream:
-1) add linux/config.h from a run of configure on a Linux development box.
-2) add SConscript and libevent.xcodeproj
-3) quotes.patch is applied to allow libevent to be used without
-being installed (alternative is adding crazy -I arguments to the commandline)
-4) The directories WIN32-Code and WIN32-Prj are not included
-
-SConscript does not include a few files that don't build on Linux:
-    devpoll.c, evport.c, kqueue.c
-libevent.xcodeproj does not include a few files that don't build on the Mac:
-    devpoll.c, epoll.c, epoll_sub.c, evport.c
-
-TODO: currently we -I the source directory, which exposes event-config.h, which
-is dangerous as this file was generated for Linux and is not entirely correct on
-other platforms.
