The directory MP/ was removed from the singular package because it had
non-DFSG free code (the license requires non-commercial use).

The directory ntl/ was removed from the singular package in order to
use the Debian ntl package from upstream sources.

The directory Singular/LIB/surfex and the file Singular/LIB/surfex.lib
were removed from the singular package because it had unclear
copyright status, had no actual java sources for the class files, and
regardless should be packaged separately should it be included in
Debian.

The Debian packaging is (C) 2008, Tim Abbott <tabbott@mit.edu> and is
licensed under the GPL, see above.
