+ * Revision 1.33 2002/04/24 02:17:47 oes
+ * - Moved get_char_param, get_string_param and get_number_param to cgi.c
+ * - Comments
+ * - Activated Jon's code for editing multiple AFs
+ * - cgi_edit_list_actions now provides context-sensitive
+ * help, looks up all action sets from standard.action and
+ * makes buttons for them in the catchall section
+ * - cgi_edit_action_submit now honors a p parameter, looks up
+ * the corresponding action set, and sets the catchall pattern's
+ * actions accordingly.
+ *
+ * Revision 1.32 2002/04/19 16:55:31 jongfoster
+ * Fixing newline problems. If we do our own text file newline
+ * mangling, we don't want the library to do any, so we need to
+ * open the files in *binary* mode.
+ *
* Revision 1.31 2002/04/18 19:21:08 jongfoster
* Added code to detect "conventional" action files, that start
