New description:
TOPCOM is a C++ program for triangulating polyhedra. More generally, it
can find a single triangulation as well as enumerate all triangulations of
a "point configuration", that is, the convex hull of points in euclidean
space such that all vertices of simplices of the triangulation are in the
given (finite) list of points.
One problem with the upstream distribution is that it statically links
many helper programs, yielding almost 200mb of binaries. Therefore, I
changed the TOPCOM build system to dynamically link TOPCOM via libtools to
reduce size
My libtoolized TOPCOM spkg is here:
http://www.stp.dias.ie/~vbraun/Sage/spkg/TOPCOM-0.16.2.p2.spkg
None of the patches in this ticket should be applied to the Sage library!
The TOPCOM binaries are (optionally) used by the patches in #9918:
triangulate point configurations.
