Noteworthy changes in release 31 (2013-09-09) [stable]

New features:

- Missing termios cc flags are now available.

Bug fixes:

- posix.tcgetattr and posix.tcsetattr no save and restore all flags,
regardless of whether they are local extensions to POSIX.

Install it with LuaRocks, using:

luarocks install luaposix-31

Until the rocks are available from the official repository in a few days,
you can install directly from the luaposix release branch, with:

$ luarocks install \
