+hyphens which are then used as fieldnames. Known values for such
+fields can be given after the second argument in arguments of the form 
+`var(fiels)tt(=)var(pattern)'. The first argument without a equal sign 
+is taken as the name of the field for which completions should be
+generated.
+
+The matches generated will be taken from the value of the style. These 
+values should contain the possible values for the combinations where
+the values for the different fields are separated by colons or the
+character given after the tt(-s) option to tt(_combination).
+
+Only the values for the requested fields for which the patterns given
+in the `var(field)tt(=)var(pattern)' match the respective fields in
+the strings from the style value are generated as possible matches.
+
+If no style with the given name is defined for the given tag but a
+function named with the name of the requestd field preceded by an
+underscore is defined, that function will be called to generate the
+matches. This is also done if none of the strings in the value of the
+style match all the patterns given as arguments.
+
+If the same name is used for more than one field, in both the
+`var(field)tt(=)var(pattern)' and the argument that gives the field
+name to complete for, the number of the field (starting with one) may
+be given after the fieldname (separated from it by a colon).
+
+All arguments after the requested fieldname are given to the
+tt(compadd) used (when generating matches from the style value) and to 
+the functions for the fields if they are called.
