Unless any errors reported themself during the install you should now
have a slashsite. You will either need to edit your httpd.conf file
unless you are have Slash handle it. The correct syntax can be found in:

	$prefix_site/$sitename/$sitename.conf

You may want to take a look at it. If you are using virtual hosting by
hostname you may also need to add a NameVirtualHost to your httpd.conf.

If you do not have your Slash site in the root of the web server (e.g.,
"http://www.example.com/mysite/" instead of "http://mysite.example.com/"),
you will need to adjust the rootdir, rdfimage, imagedir, absolutedir,
and cookiepath variables, as you also need to change your Apache config
appropriately.  These are all in the "vars" table of your database.

To restart apache do:

	apachectl stop
	apachectl start

Have fun with your new site. You should also consider registering it:

	http://slashcode.com/sites.shtml

Usage: $PROGNAME [OPTIONS]

This will create a new Slash site.  You must provide a virtual
user, which has already been set up in DBIx::Password, and the
target database must already exist and be accessible by the
given virtual user.

Main options:
	-h	Help (this message)
	-v	Version
	-u	Virtual user (default is "slash")

Site options:
	-H	Hostname
	-n	Site name
	-R	Reuse hostname as site name (boolean)
	-L	Install files in htdocs using symlinks [y/n]

User options:
	-a	Admin name
	-e	Admin email
	-p	Admin password
	-o	Installation owner
	-g	Installation group
