list of the available options. Also, use of the
|
|
<ulink url="http://www.php.net/">PHP web site</ulink>
|
|
is highly recommended, as their online docs are very good. An example of
|

a <command>configure</command> command that utilizes many of the most

common dependencies can be found at <ulink
