# 20210824 bkw: update for v4.51_8, which includes all the patches
# that used to be in patches/ here.

# 20201115 bkw: add 2 new patches from Debian git, BUILD=2.

# 20201111 bkw: added at v4.51_7. The original upstream for this is
# long gone (dead website), but the maintainer of the Debian package
# continues to develop this. So I'm treating Debian as upstream, and
# the _7 in VERSION is the Debian patchlevel.

# Japanese-language sections in the HTML docs are in some kind of

# seems to, so use lv itself to convert them to UTF-8. This is helpful
# if you're reading the files locally with a browser: there's no HTTP
# headers to specify the encoding, and UTF-8 is more likely to be
# autodetected or just guessed at.
