You're probably here because you got a message like:

	Unknown Keystone Resolver site 'fish' (host fish.somesite.com:81)
	Please see /usr/share/libkeystone-resolver-perl/db/README.sites

Keystone Resolver in general hosts several functionally similar but
cosmetically different virtual sites on a single installation: that's
so that, for example, a library consortium can run a single
installation and use it to provide separately branded resolver sites
to each of its members.

The specification of each supported site is provided by a database
record in the "site" table, and the correct site to use is chosen on
the basis of the virtual host name used to access the resolver: the
first of the "."-separated components is used, so that if for example
you access the resolver via the site "foo.bar.com", then a site record
with tag="foo" will be sought.

So if you get a message like the one above, there are two things you
can do to fix it.  One is to change the virtual host name that you use
to access the resolver, changing it to match one of those supported by
a site record in the database; the other is to add a new site record
to the database, describing your own site, and having its "tag" field
equal to the first component of the virtual host name.

To see the list of sites supported by the database, you can use SQL
like the following (assuming you are using MySQL -- details may vary
with other RDBMSs):

	mysql> select * from site;
	+----+-----------+----------------+-------------+--------------------+
	| id | tag       | name           | bg_colour   | email_address      |
	+----+-----------+----------------+-------------+--------------------+
	|  1 | id        | Index Data     | white       | mike@indexdata.com | 
	|  2 | dbc       | DBC            | lightblue   | mike@indexdata.com | 
	|  3 | talis     | Talis          | pink        | mike@indexdata.com | 
	|  4 | resolver  | Local Resolver | lightyellow | mike@indexdata.com | 
	|  5 | localhost | Localhost      | white       | mike@indexdata.com | 
	+----+-----------+----------------+-------------+--------------------+

And you can add a new site (if you connect to the database as a user
with read-write privileges on the database) with SQL like this:

	mysql> insert into site (tag, name, bg_colour, email_address) values
            -> ('fish', 'The fish portal', 'lightgreen', 'you@somesite.com');

(At the moment, customisation of the individual sites is very limited:
just background colour.  That will change, and the site objects will
become more complex.)
