Last change on this file since 2157 was 2101, checked in by lguez, 10 years ago

Exclude "out.def" of the comparison of ".def" files with
diffdef. "out.def" is neither an input file neither a file written by
IOIPSL like the files "used_*.def". So "out.def" contains some
duplicate lines with "used_guide.def", and the script diffdef would
signal that as an error.
