I just did that in a program I am writing (not extensively checked, it 
works on my Windows system):

  -- tell 'require' to look first into the directory
  -- containing this script
  local maindir = string.match(arg[0], '(.-)[^\\/]+$')
  package.path = maindir .. '?.lua;' .. package.path

  -- load required modules
  loader = require('m_loader')
  compiler = require('m_compiler')
  streamer = require('m_astream')
  coder = require('m_codegen')
  writer = require('m_writer')

(I suppose package.cpath should be changed too if C modules are required)
