Programmes written in C++

All programmes were written and tested on Intel-PCs using SuSE Linux 7.x and Debian. kovariante and invariante were also tested on SUN Sparc stations. For the sun environment the code need some minor modifications. For some of the programmes the GNU Multiple Precision Arithmetic Library (www.gnu.org) is necessary (I used version 3.1.1, but earlier versions might work as well).
