<p>Q:i have a general problem ,when i wanna to do some thing and i find the jquery file which can do exactly what i wanna to do . after a while i need another case and i find that another jquery file serve me and fix my problem .after i add set of jquery files i find conflicts among those files and some features does not work or work in awkward manner ..and when i try to find which file exactly the source for those problems i find myself in closed circle cannot modify this file or cannot delete this file or cannot find that file itself at all.sometimes the file like this:</p>

<p><code>&lt;script src="http://jqueryjs.googlecode.com/files/jquery-1.3.js" type="text/javascript"&gt;&lt;/script&gt;</code></p>

<p>cannot modify it.</p>

<p>the problem has many faces,and i cannot really know how to handle the whole matter from the beginning.</p>
