The Tela kernel has been written by me, but some auxiliary programs
and tools are not:

- the bison++ and flex++ parser and scanner generators (copyrighted
  by FSF) have been utilized

- similarly the GNU Readline library

- the PlotMTV program that is used to produce the graphics is
  copyrighted by Kenny Toh.

- the needed HDF libraries are from NCSA (Illinois, USA)

- implementations of the BLAS, LAPACK and FFT libraries can
  be obtained from Netlib

Finally, the source code of RLaB by Ian Searle was helpful when
designing the parser.
