\section{Tests}
A few words to the library's test suite. The suite resides in
directory {\tt tl/testing}. There is a file {\tt tests.cpp} which

contains all tests and {\tt main()} function. Also there are files
{\tt factory.h} and {\tt factory.cpp} implementing random generation
{\tt factory.hh} and {\tt factory.cc} implementing random generation
of various objects. The important property of these random objects is
that they are the same for all object's invocations. This is very
important in testing and debugging. Further, one can find files {\tt
monoms.h} and {\tt monoms.cpp}. See below for their explanation.
