+# Prebinding address table
+#
+# Prebinding results in improved launch times on Mac OS X <= 10.3.3.  It's
+# unnecessary when targeting >= 10.3.4.
+#
+# 0x0 to 0x4fffffff is available to the application since Mac OS X 10.2.
+# See http://developer.apple.com/documentation/Performance/Conceptual/LaunchTime/Articles/Prebinding.html
+#
+# Begin at 0x20000000, leaving space at 0x0 for the main executable image,
+# which can be large in a static debug build.
