Auxiliary functions for parsing actions.
These make it easier to build up data structures (including lists)
in the parsing actions.
/* mk_element - generic constructor for element */
element * mk_element(int key);
/* mk_str - constructor for STR element */
element * mk_str(char *string);
/* mk_str_from_list - makes STR element by concatenating a
* reversed list of strings, adding optional extra newline */
element * mk_str_from_list(element *list, bool extra_newline);
/* mk_list - makes new list with key 'key' and children the reverse of 'lst'.
* This is designed to be used with cons to build lists in a parser action.
* The reversing is necessary because cons adds to the head of a list. */
element * mk_list(int key, element *lst);
/* mk_link - constructor for LINK element */
element * mk_link(element *label, char *url, char *title, element *attr, char *id);
/* extension = returns true if extension is selected */

/* match_inlines - returns true if inline lists match (case-insensitive...) */

/* find_reference - return true if link found in references matching label.
* 'link' is modified with the matching url and title. */
