Re: run a lua page (cgilua) in command line

	Jorge,

	I thought you were trying to run the Lua Pages preprocessor,
which is not distributed separately but is really easy to use without
CGILua.  If you (or someone) want to do that just ask me.

	You just have to write a launcher for your web server
(except for the environment variables, the cgi launcher would
work for a command line test).
	A launcher is a simple file which defines the SAPI and
runs cgilua.  For example:

define_sapi ()
require"cgilua"
cgilua.main ()

	(Next version we'll change `define_sapi' to `require"sapi.launcher"'
or something like that, which makes more sense)
	The function define_sapi have to define the SAPI table:

-- untested code. partially extracted from CGILua's t_cgi.lua
SAPI = {
	Request = {
		getpostdata = function (n) return io.stdin:read(n) end,
		servervariable = function (n) return os.getenv(n) end,
	},
	Response = {
		contenttype = function (s) io.stdout:write ("Content-type: "..s.."\n\n") end,
		redirect = function (s) io.stdout:write ("Location: "..s.."\n\n")
		header = function (h, v) io.stdout:write (string.format ("%s: %s\n", h, v) end,
		write = function (s) io.stdout:write (s) end,
		errorlog = function (s) io.stderr:write (s) end,
	},
}

	Hope this helps,
		Tomas
