# More precisely, look for normal comment block containing '\'.
# Of course one could use doxygen warnings, eg with:
# sed -e '/EXTRACT/s/YES/NO/' doxygen/polarssl.doxyfile | doxygen -
# but that would warn about any undocumented item, while our goal is to find
# items that are documented, but not marked as such by mistake.
