Usage from Lua modules

To use this module from other Lua modules, first load the module.

local mLuaBanner = require('Module:Lua banner')

You can then generate a side box using the _main function.

mLuaBanner._main(args)

The args variable should be a table containing the arguments to pass to the module. To see the different arguments that can be specified and how they affect the module output, please refer to the {{Lua}} template documentation.
