gfs.xml

<?xml version="1.0"?>
<!-- generic frontend server configuration
  https://software.indexdata.com/yaz/doc/server.vhosts.html

  this configuration is passed to simpleserver with option -f, eg

  ./ztest.pl -f gfs.xml

  The retrievalInfo sections makes YAZ responsible for converting
  from XML to MARC / OPAC

  The Perl code just need to consider comp/element-set-name "marcxml" / "OP"
  to distinguish between the two cases.
