+xnec2c is a GTK+ graphical interactive version of nec2c. It incorporates
+the nec2c core which it uses for reading input files and calculating
+output data, but it does not need and indeed does not produce an output
+file by default. Since xnec2c incorporates the nec2c core, it has access
+to all internal buffers, including structure data, frequency-related
+data (structure currents, input impedance, gain etc) and radiation pattern
+data (for the far field and near field). It therefore has the ability to
+graphically display user-requested data directly, as the frequency loop
+progresses or after input from the user. Graphs of frequency-related data
+and the current or charge distribution evolve as the frequency loop
+progresses, and radiation patterns (far and near field) are sequentially
+drawn for each frequency step. A new frequency can be entered by the user
+from spin buttons in the main or radiation pattern windows or by clicking
+on the graphs of frequency-related data. New output data are then computed
+and displayed in text and graphical form.
+nec2c is a C translation of the Fortran nec2 code, which allows analysis
+of antennas.

+xnec2c: xnec2c (nec2 visualization program for X)
+xnec2c: xnec2c is the graphical counterpart of nec2c, which in turn is a
+xnec2c: port of the classic nec2 antenna visualization program from Fortran
+xnec2c: to the C programming language. xnec2c accepts nec2 output files and
+xnec2c: displays a graphical representation of the data. xnec2c uses the
+xnec2c: GTK2 graphical interface toolkit.
