TOPCOM (current version is 0.17.8, improved multi-threaded version 1.0.5 currently in test phase)
TOPCOM is a package for computing Triangulations Of Point Configurations and Oriented Matroids. It was very much inspired by the maple program PUNTOS, which was written by Jesus de Loera. TOPCOM is entirely written in C++, so there is a significant speed up compared to PUNTOS.
Meanwhile, the package MPTOPCOM by Skip Jordan, Michael Joswig, and Lars Kastner for the parallel enumeration of triangulations based, among other things, on the TOPCOM C++-library enumerates all so-called subregular triangulations (a subset of all triangulations containing the regular ones) in parallel. It is able to solve larger instances than TOPCOM. See their paper for details.

TOPCOM version 0.17.8 updates to gmp-6.1.1 and current automake/autoconf initialization. In the previous version 0.17.7, accidentally a wrong version of gmp was included. Furthermore, a bug was fixed where a new was not followed by a delete but a delete.
TOPCOM version 0.17.5 avoids a name space clash with the token "nullptr" in some gcc versions. Moreover, the configure routine now forces an install of external libraries in "external/lib" instead of "external/lib64" or the like, since this is what TOPCOM expects to be the location of external libs.
If TOPCOM turns out to be useful to you, I would be happy to hear about why. If you expected TOPCOM to be useful to you and it was not, then I would be happy to hear about why not.
At any rate: I received several questions about how to properly cite TOPCOM in research papers. I prefer a citation to the following publication:
Jörg Rambau. TOPCOM: Triangulations of Point Configurations and Oriented Matroids, Mathematical Software - ICMS 2002 (Cohen, Arjeh M. and Gao, Xiao-Shan and Takayama, Nobuki, eds.), World Scientific (2002), pp. 330-340, available as ZIB Report 02-17. (Here is a bibtex-entry.)
Remark: TOPCOM contains a program to produce a point configuration and one of its triangulation without flips as constructed by Francisco Santos in his great paper
Francisco Santos: A Point Configuration whose Space of Triangulations is Disconnected,
Journal of the American Mathematical Society 13 No. 3 (2000), 611-637.
TOPCOM can check the triangulation and compute the number of flips, which in fact is zero.
