+ * 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
+ * actionsfile.
+ *
+ * Revision 1.17 2001/10/25 03:40:47 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.16 2001/10/23 21:30:30 jongfoster
+ * Adding error-checking to selected functions.
+ *
* Revision 1.15 2001/10/14 21:58:22 jongfoster
* Adding support for the CGI-based editor:
* - Exported get_actions()
