<p>This acts much the same ways as installing on the command-line.</p>
18

    
19
<p>The &#39;where&#39; parameter is optional and only used internally, and it specifies
20
where the packages should be installed to.</p>
21

    
22
<p>The &#39;packages&#39; parameter is an array of strings. Each element in the array is
23
the name of a package to be installed.</p>
24

    
25
<p>Finally, &#39;callback&#39; is a function that will be called when all packages have been
26
installed or when an error has been encountered.</p>
