If, for debugging purposes, you want to run the program from within
the IDE without triggering errors about image and/or documentation
files not found, do the following:

- under Linux: build the program and then run once (as root) the INSTALL
  script to put everything in the proper location;

- under Windows: copy the files src\GPLv3\gpl-3.0.txt,
  src\doc\Manual-en.txt and (if required) src\doc\Manual-it.txt
  into the src\ directory.
