This is not as DRY as it could be. Furthermore I would try
implement the error handling completely outside the main
execution path, ideally in a wrapper around a the old main
function (renamed to main_). This approach becomes problematic if
exceptions of the same class can be thrown from two functions of
the chain.
Your code is printing e.msg. How to you localize that string?
