License
I believe that the best way to ensure prompt fixing of bugs in code and
feature enhancements is to make stuff open source. I chose to release
fortranposix and gnuplotfortran under the LGPL (Lesser GNU Public
License). The terms
of this license, unlike commercial licenses, permit you to use this
library freely and unlike full GPL, permit commercial programs to link
against it (please read the exact terms of the license to see what is
allowed / not allowed).
