If you want to pass the argument through a metadata on the command line (for instance with "-M docpart=doc1"), you can write:
```
local docpart = ''
local function Meta(meta)
if meta.docpart then
docpart = meta.docpart
end
end
local function Div(div)
(...)
end
-- By default, the Meta function is called after Div,
-- so the following is required.
return {
{ Meta = Meta },
{ Div = Div }
}
```
