[web2py] How to share static files between apps?

[Jemes Hsu]

What's the best way to share static files between apps? 

Let say I have 'wiki' and 'blog' applications both using the same css: 

\applications
    \wiki
    \blog
\static
    \css\bootstrap.min.css

if the css file is within an app I just use 
URL('static','css/bootstrap.min.css') to get the css file.  What should be 
the URL() let say the css file is outside of app folders like in above?
