regina-normal 5.1-6 (amd64 binary) in ubuntu disco

 Regina is a software package for 3-manifold and 4-manifold topologists,
 with a focus on triangulations, normal surfaces and angle structures.
 .
 For 3-manifolds, it includes high-level tasks such as 3-sphere recognition,
 connected sum decomposition and Hakenness testing, comes with a rich
 database of census manifolds, and incorporates the SnapPea kernel for
 working with hyperbolic manifolds. For 4-manifolds, it offers a range of
 combinatorial and algebraic tools, plus support for normal hypersurfaces.
 .
 Regina comes with a full graphical user interface, as well as Python bindings
 and a low-level C++ programming interface.
 .
 This package includes the graphical user interface and the command-line
 Python interface. The users' handbook and the API documentation are in
 the separate package regina-normal-doc, and the MPI-enabled utilities for
 high-performance clusters are in the separate package regina-normal-mpi.
