The include function can be used to simplify reuse of common functionality shared between multiple remotes.
For example you may have a set of actions or functions that you want to use in multiple variations of a remote.
You could place this in a file called common.lua.
Remotes/
Example/
common.lua
Foo/
meta.prop
remote.lua
Bar/
meta.prop
remote.lua
In the implementation for each remote you could then include the common file and use whatever you placed in there.
For example, in the remote.lua file for the Foo remote:
include("../common.lua")
actions.foo = function ()
func_from_common("foo");
end
