1This is Lua 1.0. It was never publicly released. This code is a snapshot of
2the status of Lua on 28 Jul 1993. It is distributed for historical curiosity
3to celebrate 10 years of Lua and is hereby placed in the public domain.
4
5There is no documentation, except the test programs. The manual for Lua 1.1
6probably works for this version as well.
7
8The source files for the lexer and parser have been lost: all that is left is
9the output of lex and yacc. A grammar can be found inside y_tab.c in yyreds.
10
11The code compiles and runs in RedHat 5.2 with gcc 2.7.2.3. It may not run in
12newer systems, because it assumes that stdin and stdout are constants, though
13ANSI C does not promise they are. If make fails, try using the fixed modules
14provided in the "fixed" directory. To see the differences (which are really
15quite minor), do "make diff".
16
17To see Lua 1.0 in action, do "make test". (The last test raises an error on
18purpose.)
19
20Enjoy!
