 ## This way you can write a ufl file and compile it obtaining a LinearForm.
 ##
+## Be aware that a ufl line starting with brackets will result in a syntax
+## error. To avoid this, it is necessary to enclose them and their content
+## in quotes or apices:
+## @example
+## @code{ufl "(sigma, u)" = TrialFunctions(W)}
+## @end example
