#Building MiniBPM

Just add MiniBpm.h and MiniBpm.cpp (found in the src/ directory here) to your code project. The code is C++98 standard. MiniBPM uses some classes from the C++ standard library, but has no other dependencies.

A suite of unit tests is provided using the Boost test framework. (Note that these test the implementation of the method -- they do not give you any indication of how good the method itself is.) To run them, run make or equivalent in the tests/ directory.
