       The   development   of  "simple2zoom",  and  the  "Net::Z3950::Simple2ZOOM"  library  that  provides  its
       functionality, has been partially sponsored by the National Library of Australia, whose  contribution  we
       gratefully acknowledge.

       "simple2zoom" provides a generic gateway between the Z39.50 and SRU/SRW Information Retrieval protocols.
       Because it relies on the "Net::Z3950::SimpleServer" and "ZOOM" modules for the server and client
       funcationality respectively, because both of these modules are based on the YAZ toolkit, and because YAZ
       transparently handles all three standard IR protocols (ANDI/NISO Z39.50, SRU and SRW), it can function as
       a gateway from any and to any of these protocols.  However, its principle purpose is as a Z39.50 server
       that proxies requests through to a backend by acting as an SRU client.

       The following command-line options govern how the gateway functions:

       -c configFile
           Specifies  that the named configFile should be used to configure the functionality of the gateway: if
           this option is not specified, then the file "client.xml" is used.  The format  of  the  configuration
           file  is  described separately in "Net::Z3950::Simple2ZOOM::Config", and a sample configuration file,
           "test.xml", is supplied in the "etc" directory of the distribution.

       --  Indicates the end of "simple2zoom"-specific options.  This is required  if  YAZ  options  are  to  be
           specified, so that "simple2zoom" doesn't try to interpret them itself.

       YAZ-options
           Command-line  arguments  subsequent  to  the "--" option are interpreted by the YAZ backend server as
           described at http://www.indexdata.dk/yaz/doc/server.invocation.tkl

           These options provide the means to control many aspects of the gateway's  functioning:  for  example,
           whether the server forks a new process for each client or runs a single process using "select()"; how
           (if  at  all)  to  interpret  incoming  SRU  requests;  whether  and  how to log protocol packets for
           debugging.

       listener-address
           One or more YAZ-style listener addresses may be specified, and the server will accept connections  on
           those addresses: for example, @:9998, "unix:/tmp/somesocket" or "ssl:myhost.com:210".  If no explicit
           listener addresses are provided, the server listens on port 9999.
