/* History:
* --------
* 2003-01-29 s/int/enum ... more convenient for gdb (jiri)
* 2003-03-31 added subst lumps -- they expand in ip addr, port a.s.o (andrei)
* 2003-04-01 added opt (condition) lumps (andrei)
* 2003-04-02 added more subst lumps: SUBST_{SND,RCV}_ALL
* => ip:port;transport=proto (andrei)
* 2005-03-22 the type of type attribute changed to enum _hdr_types_t (janakj)
