+# tarball as pd-faustgen-<version>.tar.gz in the toplevel directory. Temporary
+# data is written to the pd-faustgen-<version> directory, which is
+# automatically deleted afterwards. The version number is extracted from
+# src/faustgen_tilde.c, so make sure to keep that up-to-date.
+
+# NOTE: git and tar need to be installed to make this work. As a side-effect,
+# all submodules will be checked out recursively, using `git submodule update
+# --init --recursive`.
+
+# This may need adjusting if the file is edited and the macro name changes.
