The point of Boost Exception is to augment exceptions in flight regardless
of their exact type. At the point of the throw, you don't typically have
all relevant information to put in the exception object, for example when
reporting a file read error you don't have the file name available. Boost
Exception allows you to add file names and anything else later on.
