Note that -i and -t are incompatible.  The former fully specifies an
instance name for Gantry::Conf.  The later specifies the config type
suffix of an instance name.  If you use both, -t takes precedence.

-d defaults to SQLite.

=head1 NAME

app.server - A generated server for the Kids app

=head1 SYNOPSIS

    usage: app.server [options] [port]

port defaults to 8080

=head1 DESCRIPTION

This is a Gantry::Server based stand alone server for the Kids
app.  It was built to use the kids Gantry::Conf instance in the
docs directory.

To override the database connection information in your conf file,
see L<Changing Databases without Changing Conf> below.

To change instances or master conf files, use these
flags (they all require values):

=over 4

=item --instance (or -i)

(Incompatible with --type)

The full name of your conf instance, defaults to kids.

=item --type (or -t)

(Incompatible with --instance)

Use this if you use named config blocks in your Bigtop file.  Use the
name of the config block as the value for --type.  This will build the
corresponding instance name as kids_TYPE, where TYPE is the value
of this flag.

If you don't neither --instance nor --type, the instance you get will
be kids.

=item --file (or -f)

The name of your master Gantry::Conf file, defaults to docs/app.gantry.conf.

=back

=head1 Changing Databases without Changing Conf

You may use the following flags to control database connections.  If you
supply these flags, they will take precedence over your Gantry::Conf instance.
All of them require values.

=over 4

=item --dbd (or -d)

The name of your DBD module (like SQLite, Pg, or mysql).  If you use
dbname, this defaults to SQLite.

=item --dbname (or -n)

The name of your database.

=item --dbuser (or -u)

Your database user name.

=item --dbpass (or -p)

Your database password.
