J.3.7 Release MD-2.1

$\bullet$ Literate Programming: trying CTEX embedded comments in e.g. the potential descriptors, and anisot.c

$\bullet$ Properly documented and advertised use of using binary structured files in pipes.

$\bullet$ Some support for Starlab in the form of NEMO++. Translation programs to convert from a dyn to a snapshot have been written. Apart from properly ANSI-coding the NEMO kernel, the routine nemomain.c needs to be present in C++ format too: nemomain.C.

$\bullet$ Potentials are now supposed to return a pattern speed (even if it was not changed) into the first argument of the potpars array. This to deal with rotating potentials.
