 RiscLua is a port to RISC OS of the Lua programming language. It differs from standard Lua in a few small details to be more conformant to RISC OS. The packaging of RiscLua has also varied. At one point it was a relocatable module, but it was found that error-handling was easier when packaged as an application.
