/******************************* DTOEINIT.C ********************************
* $XConsortium: dtoeinit.c /main/6 1996/11/21 19:49:29 drk $
* Sept 1991.
* Contains oe_initialize() function from universal "Opera Engine" code.
* Has been separated out because it is the largest function and
* needs to be tested separately.
*
* $Log$
* Revision 2.4 1996/03/13 22:52:04 miker
* Enabled several language loading debug requests from API.
*
* Revision 2.3 1995/10/25 21:59:27 miker
* Renamed from oeinit.c. Added prolog.
*
* Log: oeinit.c,v
* Revision 2.2 1995/10/02 20:39:22 miker
* Added zbflags arg to load_semantic().
*
* Revision 2.1 1995/09/22 21:38:53 miker
* Freeze DtSearch 0.1, AusText 2.1.8
*
* Revision 1.14 1995/09/05 18:58:01 miker
* Changed all socblk refs to universal, global usrblk (no more merges).
* Deleted numerous globals. Added DTSEARCH define.
* Conflated all msglists to one ausapi_msglist. All for DtSearch...
