Thomas Moschny passed along a request from the Fedora packagers which came

up during the Fedora submission review, that each source file include some
text about the license. One handy Perl script later and each file now has
the line
   Distributed under the terms of the Botan license
after the copyright notices.

While I was in there modifying every file anyway, I also stripped out the
remainder of the block comments (lots of astericks before and after the
text); this is stylistic thing I picked up when I was first learning C++
but in retrospect it is not a good style as the structure makes it harder
to modify comments (with the result that comments become fewer, shorter and
are less likely to be updated, which are not good things).
