-- Lua 5.0/5.1 init file for Kepler
--
-- Prepares the paths for Lua and C modules using three parameters:
--    conf    - configuration files (optional, checked before the Lua modules)
--    luabase - Lua modules
--    libbase - C modules
--
-- (the paths should end in /)
--
-- Defines the default web directory for Lua Pages and Lua Scripts
