Thanks, mdi and Jonathan. I will borrow your __cssheaders() function,
if you don't mind.
Is there any way to have some code in the css.py controller which will
automatically define functions for all my css files in /views/css/ ?
All it would need to do is run the __cssheaders() function and return
dict(), but it feels unnecessary to maintain a list of functions when
there are files.
