calculates positions on orbits of celestial bodies and the total velocity change
Delta-v for transfer trajectories between them with rocket burns at departure and
arrival only. It can do a scan to find the departure and arrival times that yield
the lowest Delta-v. Alternatively, one can also minimize the departure Delta-v only
for missions to intercept the target body without velocity matching.

This program can do only planar geometries, ignoring orbital inclinations. It is now
superceded by the program
can do three-dimensional geometries, and more capable in other ways, too.
