+ * name from a map.

+ * Revision 1.9 2001/10/23 21:21:03 jongfoster
+ * New error handling - error codes are now jb_errs, not ints.
+ * Changed the way map() handles out-of-memory, to dramatically
+ * reduce the amount of error-checking clutter needed.
+ *
+ * Revision 1.8 2001/09/16 17:30:24 jongfoster
+ * Fixing a compiler warning.
+ *
+ * Revision 1.7 2001/09/16 13:20:29 jongfoster
+ * Rewrite of list library. Now has seperate header and list_entry
+ * structures. Also added a large sprinking of assert()s to the list
+ * code.
+ *
+ * Revision 1.6 2001/08/05 16:06:20 jongfoster
+ * Modifiying "struct map" so that there are now separate header and
+ * "map_entry" structures. This means that functions which modify a
+ * map no longer need to return a pointer to the modified map.
+ * Also, it no longer reverses the order of the entries (which may be
+ * important with some advanced template substitutions).
+ *
+ * Revision 1.5 2001/07/29 18:43:08 jongfoster
+ * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
+ * ANSI C rules.
+ *
+ * Revision 1.4 2001/06/29 13:30:37 oes
+ * - Introduced enlist_unique_header()
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.3 2001/06/03 11:03:48 oes
+ * introduced functions for new list type "map": map(), lookup(),
+ * free_map(), and extended enlist_unique
+ *
+ * Revision 1.2 2001/06/01 18:49:17 jongfoster
+ * Replaced "list_share" with "list" - the tiny memory gain was not
+ * worth the extra complexity.
+ *
+ * Revision 1.1 2001/05/31 21:11:53 jongfoster
+ * - Moved linked list support to new "list.c" file.
+ * Structure definitions are still in project.h,
+ * function prototypes are now in "list.h".
+ * - Added support for "struct list_share", which is identical
+ * to "struct list" except it saves memory by not duplicating
+ * the strings. Obviously, this only works if there is some
+ * other way of managing the memory used by the strings.
+ * (These list_share lists are used for lists which last
+ * for only 1 request, and where all the list entries are
+ * just coming directly from entries in the actionsfile.)
+ * Note that you still need to destroy list_share lists
+ * properly to free the nodes - it's only the strings
+ * which are shared.
