Many improvements such as support for mixed dielectric systems and several
bitmap generators for common structures to allow quick application of the
tool. Several bug fixes as well. Voltages outside a shield are set to zero
which fixes a reported result in older versions. Many other improvemnts
and bug fixes are listed in the ChangeLog in the distfile.

Atlc is a finite difference programme that is used to calculate the
properties of a two-conductor electrical transmission line of
arbitrary cross section. It is used whenever there are no analytical
formula known, yet you still require an answer. It can calculate:
The impedance Zo (in Ohms)
The capacitance per unit length (pF/m)
The inductance per unit length (nF/m)
The velocity of propogation v (m/s)
The velocity factor, v/c, which is dimensionless.
A bitmap file (usually with the extension .bmp or .BMP) of the cross
section of the transmission line is drawn in a graphics package such
as The Gimp and then analyzed using Atlc.
