/*
  This file defines the composition for Lua packages.  It has
  been factored out of all-packages.nix because there are many of
  them.  Also, because most Nix expressions for Lua packages are
  trivial, most are actually defined here.  I.e. there's no function
  for each package in a separate file: the call to the function would
  be almost as must code as the function itself.
