   $Log$
   Revision 1.11  1999/10/25 22:29:32  sjboddie
   receptionist now checks collect diectory for collections
   rather than collections.txt file

   Revision 1.10  1999/10/19 03:23:43  davidb
   Collection building support through web pages
   and internal and external link handling for collection documents

   Revision 1.9  1999/09/07 04:56:56  sjboddie
   added GPL notice

   Revision 1.8  1999/06/27 22:04:47  sjboddie
   now read in build.cfg before collect.cfg so that the indexmaps
   are available if required to decode defaultindex, defaultsubcollection,
   and defaultlanguage

   Revision 1.7  1999/06/15 02:16:45  sjboddie
   small change to prevent collectdir configuration string from being passed
   to everything

   Revision 1.6  1999/05/10 03:40:41  sjboddie
   lots of changes - slowly getting document action sorted out

   Revision 1.5  1999/04/30 01:59:41  sjboddie
   lots of stuff - getting documentaction working (documentaction replaces
   old browseaction)

   Revision 1.4  1999/03/31 23:44:48  rjmcnab
   Altered the protocol so that the metadata is part of the filter.

   Revision 1.3  1999/03/03 23:26:35  sjboddie

   Implemented more of the protocol

   Revision 1.2  1999/02/25 21:58:58  rjmcnab
