=head1 NAME

lr_check_superservice - map Lire service to Lire superservice

=head1 SYNOPSIS

B<lr_check_superservice> I<service>
B<lr_check_superservice> B<-l>

=head1 DESCRIPTION

B<lr_check_superservice> takes a Lire service as argument, and returns the
I<superservice> this I<service> belongs to.  In case the service is unknown, a
userfriendly errormessage is given.

When called with the B<-l> option, this script prints all supported
superservices.

You might prefer the lr_log2report(1) --help options to list available
superservices: this command creates a more human-friendly format of the list.

=head1 EXAMPLE

Call this script in shell scripts as

 LR_SERVICE="$1"

 LR_SUPERSERVICE=`lr_check_superservice "$LR_SERVICE" || true`
 if test -z "$LR_SUPERSERVICE"
 then
    echo >&2 "$tag err lr_check_superservice failed"
    exit 1
 fi

 # now go using $LR_SUPERSERVICE
