+Setting up Autoconf
+~~~~~~~~~~~~~~~~~~~
+The ``amuse_deps`` file we just created informs the ``AMUSE`` build system about whether or not our
+package is buildable given the available compilers and libraries detected on your computer. We now need
+to determine what compilers and libraries are on the system and how to use them. For this we will edit
+the ``configure.ac`` file in ``amuse_tidymess/support/``. This file contains a set of macros which will
+detect the tools and libraries needed to build our package. The template should contain all the macros
+needed for our package, so its just a matter of deleting what we don't need.
+
+.. WARNING::
+
+    Make sure the the ``amuse_tidymess/support/shared/`` folder is a simlink to ``amuse/support/shared/``
+    to ensure that there is no code duplication in the codebase, and that bug fixes are propagated to each
+    package automatically.
