+### AIX Notes
+
+AIX support for filesystem events requires the non-default IBM `bos.ahafs`
+package to be installed.  This package provides the AIX Event Infrastructure
+that is detected by `autoconf`.
+[IBM documentation](http://www.ibm.com/developerworks/aix/library/au-aix_event_infrastructure/)
+describes the package in more detail.
+
+AIX support for filesystem events is not compiled when building with `gyp`.
