[[Copyleft]] free to modify and free in cost software is strongly preferred over other solutions. Minimal modifications required could be another preference as that means maintenance of the chosen solution is minimized in that aspect. | [[Copyleft]] free to modify and free in cost software is strongly preferred over other solutions.
