[Charlug] GPL vs. LGPL

[Pierre Abbat]

I'm writing a program to compute topography for land surveys, using a method 
that is better than the one currently in use. It's a standalone executable, 
using stdin and stdout (or cin and cout - it's in C++ and I don't yet have my 
head around all the C++ stuff), and will read points from commonly used point 
file formats and output contours as PostScript, DXF, and probably other 
formats. The way to get widest use of it, though, is to integrate it into 
Land Desktop, a commercial program which runs on top of AutoCAD and is used 
by surveyors to draw maps. Interfacing a text program to AutoCAD is not hard. 
The program currently has a GPL COPYING file, which is the default provided 
by KDevelop or by the auto scripts. I'm thinking that it should be LGPL, 
since it has to be run from Land Desktop to be of much use. What do you 
think?
