What?

linSmith is a Smith Charting program, mainly designed for educational
use. As such, there is an emphasis on capabilities that improve the
'showing the effect of'-style of operation.

It's main features are:

	-Definition of multiple load impedances (at different frequencies)

	-Addition of discrete (L, C and transformer) and line components
	 (open and closed stubs)

	-Connection in series and parallel

	-A 'virtual' component switches from impedance to admittance to
	 help explaining (or understanding) parallel components

	-The chart works in real impedances (not normalized ones)

	-Direct view of the result on the screen

	-Ability to generate publication quality Postscript output

	-A 'log' file with textual results at each intermediate step

	-Load and circuit configuration is stored separately, permitting
      	 several solutions without re-defining the other (this may actually
         change to single files - I'm not quite convinced here)


License

	I've released this program under the GNU General Public License.

To-do list

	-Arrows to the connecting lines and arcs
	-Labels to the impedances
	-Input of impedances as S-parameters (maybe Y-parameters too)
	-Optional lines through points indicating wavelengths
	-Export the numeric impedance list to a text file (csv?)
	-Export of a screen shot of the map (but not just the visible
	 part) to an image file
	-Make the points moveable by dragging them on the chart (the
	 handler is already in place)
	-Some kind of auto-optimization?
	-Automatically generate a legend of the colors used.
