+wxAutohacks
+
+wxAutohacks is a way of ensuring the configure script remains consistent
+between developer commits.  Previous releases include a build/aclocal_include
+which has now been moved into the wxWidgets build/aclocal directory.
+
+At the moment, it is intended to be copied and or symlinked into a wxWidgets
+source tree.  For example, assume you have wxWidgets checked out in the
+/home/myname/wxCVS/wxWidgets/ path.  Then from /home/myname/wxCVS do this:
+cvs -d :pserver:anoncvs@cvs.wxwidgets.org:/pack/cvsroots/wxwidgets checkout wxAutohacks
+
+You will now have wxAutohacks in /home/myname/wxCVS/wxAutohacks/.  Now go into
+the wxWidgets build (/home/myname/wxCVS/wxWidgets/build/) and do this:
+ln -s ../../wxAutohacks/build/autoconf_prepend-include .
+
+From now on from the root of your wxWidgets source tree when you do this:
+make -f build/autogen.mk
+you will also build an autoconf.m4f file which will ensure the configure
+script stays consistent.
+
+Alternatively you can do this:
+make -f build/autogen.mk AUTOHACKS_PREPEND_INCLUDE_DIR=../wxAutohacks/build/autoconf_prepend-include
