and luapp.lua somewhere in your $LUA_PATH. luapp module exports only

@root-name -- optional name for the topmost table if you expect it to
be recvursive, default: "ROOT"
@page-width -- optional max page width, default: 78
@max-line-with -- optional fraction of the max desired line width to
the page width, default: 0.6
