Hi Hisham,
We could just do it like others do it: store assets besides script code. I have
created many ruby gems and there is no such restriction with the their
deployment strategy: it is common place to store assets inside the gem (for
example, the "Ruby on Rails" gem contains "view.html.erb" files right inside
"lib").
Since the assets end in ".js" or ".css", there is no risk of trying to load
these as Lua files by doing require "lub.doc.css.bootstrap" or some other silly
thing. The extension is already a good and properly working filter: no need to
add some other filtering scheme based on file paths.
Finding them is then trivial, for the code itself and for users: just browse
around the code. For example lub.path (http://doc.lubyk.org/lub.html#path) uses
the debug library to find running script path so this is robust and relocatable.
