Scientific programming in field theory. 2

For pt.1 see ibid., vol.3, no.3, p.66-74 (2001). As the first part of this two part article explained, TETlib, the theoretical electrical engineering toolkit, is an object oriented C++ library that we designed for basic purposes in field theory. The last issue described its software engineering aspects. The second part addresses its field theory aspects, introducing its main classes to give an overview of the functionality involved.
