How about using a macro for the some pages situation? E.g.

def macro_InjectJSorCSS(macro, _trailing_args=[]):

    args = {'jquery':'http://code.jquery.com/jquery.min.js',
            'somejs':/server/path/to/somejs.js',
            'somecss':'/filesystem/path/to/somecss.css'}

    html = ''
    for arg in _trailing_args:
        src = args[arg]

        if src.endswith('js'):
            html += '<script type="text/javascript" src="%s"></script>' %
src
        else:
            html += '<style type="text/css">' + open(src, 'r').read() +
'</style>'

    return macro.formatter.rawHTML(html)

Thus, InjectJSorCSS(jquery,somejs,somecss)

The content of CSS files is injected into the page as the <link> statement
is restricted to the head.
