# Sometimes CHANGES is present, sometimes it isn't.
# We don't care about noise on stderr.  Better than missing docs.
# So, first we try to copy it:
mkdir -p $PKG/usr/doc/radeontool-$VERSION
cp -a CHANGES $PKG/usr/doc/radeontool-$VERSION
# Then we take care of any empty directory in case there was no CHANGES file:
rmdir $PKG/usr/doc/radeontool-$VERSION
rmdir $PKG/usr/doc
