Usage: 
makesite [--driver=<driver_name>] <site_path> <db_user>:<db_pass>@<db_host>/<db_name> <dataface_url>
or
php makesite <site_path> <db_user>:<db_pass>@<db_host>/<db_name> <dataface_url>
	where 
	<driver_name>      = The database driver to use.  Current options are
                         mysql and mysqli.  Default is mysqli.
	<site_path>        = The path to your application directory.
	<db_user>	       = The MySQL username to connect to the database
	<db_pass>	       = The User's password to connect to the database
	<db_host>	       = The MySQL host name.
	<db_name>	       = The name of the mysql database for the application.
	<dataface_url>     = The URL to the dataface installation
	
Examples:

makesite --driver=mysqli ../FacultyOfWidgetry \
 root:pass@localhost/FacultyOfWidgetry /dataface

The above command would create a site at ../FacultyOfWidgetry (i.e., the
Faculty of Widgetry directory in the parent directory.  The database
used for this site is located at localhost, and the database name is
FacultyOfWidgetry. The username to connect to the database is root and
his password is password.
