-in this case the first word can be word1 or word11 followed by an a, b or c, and if the first word contains 11 then a second
-word is allowed which can be word2 or word22 followed by and a, b, or c.
+In this example, the command itself is matched first (any non-empty word). The first argument
+can be either =word1(a|b|c)= or =word11(a|b|c)=. If the first argument matches the =word11=
+variant, a second argument becomes available, which can be either =word2(a|b|c)= or
+=word22(a|b|c)=.
 
 If this sounds too complicated a much simpler alternative is to use the _regex_words function for creating
 specifications for _regex_arguments.
