%description
This project has two uses:
- An alternative to the standalone interpreter included with Lua, one that
supports things like plugins, tab completion, and automatic insertion of
return in front of expressions.
- A REPL library you may embed in your application, to provide all of the
niceties of the standalone interpreter included with Lua and then some.
