  On Unix, you can do this:

	GenericUnixPrompt> LUA_PATH="./?.lua" LUA_CPATH="" lua

  Other systems not so much, so yes, I could see adding a "-path" and
"-cpath" to the Lua interpreter.

  That would be "lua -e 'luacode' -i"

  All together then:

GenericUnixPrompt> lua -lorg.conman.table -e 'show=org.conman.table.show' -i
