ah, a real-world example. Just what we need. Care to write a short pod
section using this example, explaining the problem and the solution?
plain text or pod will do. we will add it to the coding chapter.


Hmm, let's use my english-like language...

The problem:
- the application static files are installed in /myapp/img,
  /myapp/css, ...
- local site customization can be made by installing customized files
  in /custom/img, /custom/css...
- in both cases they are accessed via /img/..., /css/... urls
The solution - we use custom transhandler to check whether the
customized version exists and use it if so.
Yes, but can you write a section to be added to the documentation, explaining 
the problem, providing an example and a solution. Something that you'd have 
loved to find in the docs, when you first discovered it? Of course digesting 
all the helpful comments from others in this thread.

Good docs don't grow on the trees, someone has to put them together.
