features are problematic here. So, if we do not want ``configure`` to
guess its settings we **must disable everything we do not want**.
+To support this process, PTXdist supplies a helper script, located at
+``/path/to/ptxdist/scripts/configure-helper.py`` that compares the configure
+output with the settings from ``FOO_CONF_OPT``:

+In this example, many configure options from libsigrok (marked with ``+``)
+are not yet present in ``LIBSIGROK_CONF_OPT`` and must be added, possibly also
+by providing more dynamic options in the package definition.

Since every optional parameter adds four lines of code to the rule
files, PTXdist provides some shortcuts to handle it. Refer to section
:ref:`param_macros` for further details.
