-These are simple tests for Lua.  Some of them contain useful code.
-They are meant to be run to make sure Lua is built correctly and also
-to be read, to see how Lua programs look.

-Here is a one-line summary of each program:
-
-   bisect.lua		bisection method for solving non-linear equations
-   cf.lua		temperature conversion table (celsius to farenheit)
-   echo.lua             echo command line arguments
-   env.lua              environment variables as automatic global variables
-   factorial.lua	factorial without recursion
-   fib.lua		fibonacci function with cache
-   fibfor.lua		fibonacci numbers with coroutines and generators
-   globals.lua		report global variable usage
-   hello.lua		the first program in every language
-   life.lua		Conway's Game of Life
-   luac.lua	 	bare-bones luac
-   printf.lua		an implementation of printf
-   readonly.lua		make global variables readonly
-   sieve.lua		the sieve of of Eratosthenes programmed with coroutines
-   sort.lua		two implementations of a sort function
-   table.lua		make table, grouping all data for the same item
-   trace-calls.lua	trace calls
-   trace-globals.lua	trace assigments to global variables
-   xd.lua		hex dump
