annotate m4/check-math-lib.m4 @ 12518:b5e42ef33b49
update nearly all FSF copyright year lists to include 2009
The files named by the following are exempted:
grep -v '^#' config/srclist.txt|grep -v '^$' \
| while read src dst; do
test -f "$dst" && { echo "$dst"; continue; }
test -d "$dst" || continue
echo "$dst"/$(basename "$src")
done > exempt
git ls-files tests/unictype >> exempt
In the remaining files, convert to all-interval notation if
- there is already at least one year interval like 2000-2003
- the file is maintained by me
- the file is in lib/uni*/, where that style already prevails
Otherwise, use update-copyright's default.
