DESCRIPTION

The \fIREGDB\fR task is used to query or manage the local registry database
file defined by the VO package \fIresdb\fR parameter.  A local registry
database allows tasks to use preferred resources without generating a 
query to the VO Registry each time information about the resource is 
needed (e.g. the service URL), or to refer to a resource by a user-defined
alias.  The \fIarg1\fR parameter may be either a command to manage the
database, or a search term for the database, in all cases the results are
written to the standard output.

Searches may be constrained by setting the \fItype\fR or \fIbandpass\fR
parameter to match only those records meeting the constraints.  This can
be used for example to select the image service in a registry database
containing multiple services with the same name alias.

.ih
COMMANDS

If the first argument to the task is not in the following list of allowed
commands, it is assumed to be a search term.  Record searches are done 
as case-insensitive substring matches against all the saved fields of 
the record.

The following commands are supported:

.nf
    list	List the registry database records
    resolve	Resolve (search) for the \fIarg2\fR string
    search	Search for (resolve) the \fIarg2\fR string

    type	Print the service type for records matching \fIarg2\fR
    alias	Print the DB alias for records matching \fIarg2\fR
    bpass	Print the bandpass value for records matching \fIarg2\fR
    ivorn	Print the VO identifier for records matching \fIarg2\fR
    sname	Print the VO ShortName for records matching \fIarg2\fR
    url		Print the ServiceURL for records matching \fIarg2\fR
    desc	Print the Description for records matching \fIarg2\fR

    add		Add a record for the service
    del		Delete the record that matches the \fIarg2\fR string
    update	Do a new Registry query and update the local DB
    rename	Rename the local record alias

.fi

2) Print the URL for the DSS service in the registry database. 
.nf
  votools> regdb url alias="dss"
.fi
