-- | -- NAMESPACE DETECT -- | ||
-- | -- -- | ||
-- | -- This module implements the {{namespace detect}} template in Lua, with a -- | ||
-- | -- few improvements: all namespaces and all namespace aliases are supported, -- | ||
-- and namespace names are detected automatically for the local wiki. The -- | |||
-- module can also use the corresponding subject namespace value if it is -- | |||
-- | -- used on a talk page. Parameter names can be configured for different wikis -- | ||
-------------------------------------------------------------------------------------- | -- by altering the values in the "cfg" table in -- | ||
-- Module:Namespace detect/config. -- | |||
