If make succeeds, you get an interpreter in ./bin/lua. The libraries are in ./lib. The include files are in ./include. You don't need the other directories for development. - There is documentation in ./doc and tests in ./test. - The documentation includes a reference manual and an article on the - design and implementation of Lua. + There is a reference manual in ./doc and tests in ./test. This distribution is biased towards SunOS 4 with gcc but it is simple to change the Makefiles for other systems. + If you are running SunOs, type also "domake dynamic" to build shared + libraries in ./lib. * Legal matters - Lua is not in the public domain; TeCGraf keeps its copyright. - Nevertheless, Lua is freely available for academic purposes by anonymous ftp - at ftp.icad.puc-rio.br:/pub/lua/lua-1.1.tar.Z. - For commercial purposes, please contact us. + Lua is now freely available for both academic and commercial purposes. + Lua is not in the public domain; TeCGraf keeps its copyright. * Contacting the authors Send your comments, bug reports and anything else to lhf@icad.puc-rio.br.
