Module:Buffer

--[[ This module was created by User:CodeHydro (Alexander Zhikun He). User:Jackmcbarn and User:Mr._Stradivarius provided a great deal of assistance in writting p.main

p.main draw heavily from the following version of Template:Asbox of the English Wikipedia, authored primarily by User:Rich_Farmbrough https://en.wikipedia.org/w/index.php?title=Template:Asbox&oldid=619510287

p.templatepage is derived from the following revision of Template:Asbox/templatepage, authored primarily by User:MSGJ https://en.wikipedia.org/w/index.php?title=Template:Asbox/templatepage&oldid=632914791
