		  be transformed in just one.
		* translatable string starting with underscores (<code>_</code>) are reserved. You
		  *cannot* use translatable phrases starting with an underscore.
		* Make sure that the translatable string is _constant_. Specially, do *not*
		  include <code>%<nop>VARIABLES%</code> inside the translatable strings
