eXeScope is a program that allows modifying texts and images that appear in an application.
eXeScope translates programs. This is to say if there is a program that has the buttons and menus in english, with this software you will be able to edit them and to translate them to spanish. However, the translation is responsibility of the user :) Also you will be able to change the graphs that come along with the program. Not apt for inexpert users :)
