Export Expense Receipts

I like the "Expense" feature and the ability to upload directly the "Receipt". I use it to take a photo of my restaurant bills or to upload the PDF of my train/flight tickets.

But you can export the list of expenses but not the receipts and I need it for my accountant and for my clients (billable expenses)

So I developped a little script in Ruby to check my account and download all the receipts in a directory tree by client / project
