OpenCPN source -- repacked tarball.
-----------------------------------

The original upstream sources contains files which for various reasons
(binaries without source, licensing, bundled libraries) cannot go into 
the source tarball used by debian. This is documented in the
Files-Excluded stanza in debian/copyright.

Since the Files-Excluded tag is supported by devscripts since at least
2.18-3, this should be enough to download the latest sources using
uscan. However, at the time of writing this does not work as described
in #831870. A workaround is implemented in debian/rules; the way to
download sources is for now

    make -f debian/rules get-orig-source
