NAME

       simple2zoom - generic Swiss Army Server for proxying between IR standards

SYNOPSIS

       "simple2zoom" [ "-c" configFile ] [ "--" YAZ-options ] [ listener-address ...  ]

DESCRIPTION

       "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.
