[ANN] updated my libraries and tools for Lua

[Luiz Henrique de Figueiredo <lhf@...>]

I've updated most of my libraries and tools for Lua:
        http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/

I recommend anyone who uses a previous version of these packages to
move to the new ones. The code has been revised and improved.

The code now works for Lua 5.1 and later and so there is only one
package for each library and tool, not one for each Lua version.

The packages are self-contained and include third-party libraries when needed.

The packages have a version number in preparation for LuaRocks.

The packages build out of the box in Linux and macOS, if Lua is installed
in /usr/local. Otherwise, tell make:
        make LUA_TOPDIR=/var/tmp/lhf/lua-5.3.5/install

To install a library where Lua can find it, use a variant of these:
        make install
        sudo make install
        sudo make install LIBDIR=/usr/local/lib/lua/5.3

Checksum and other data available at
       http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/release.txt

These packages are in the public domain and also under the MIT license.
Third-party libraries have their own licenses.

Enjoy. All feedback welcome.
