+ *
+ * Revision 1.24 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.23 2002/03/07 03:46:16 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.22 2002/01/21 00:27:02 jongfoster
+ * Allowing free_action(NULL).
+ * Moving the functions that #include actionlist.h to the end of the file,
+ * because the Visual C++ 97 debugger gets extremely confused if you try
+ * to debug any code that comes after them in the file.
+ *
+ * Revision 1.21 2002/01/17 20:54:44 jongfoster
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Revision 1.20 2001/11/22 21:56:49 jongfoster
+ * Making action_spec->flags into an unsigned long rather than just an
+ * unsigned int.
+ * Fixing a bug in the display of -add-header and -wafer
+ *
+ * Revision 1.19 2001/11/13 00:14:07 jongfoster
+ * Fixing stupid bug now I've figured out what || means.
+ * (It always returns 0 or 1, not one of it's paramaters.)
+ *
* Revision 1.18 2001/11/07 00:06:06 steudten
* Add line number in error output for lineparsing for
