//@PURPOSE: Provide a trait to mark types that use 'bslma' allocators.
//
//@DEPRECATED: Use 'bslma_usesbslmaallocator' instead.
//
//@CLASSES:
//  bslalg::TypeTraitUsesBslmaAllocator: uses 'bslma' allocators
//
//@SEE_ALSO: bslalg_constructorproxy
//
//@DESCRIPTION: This component provides a single traits class,
// 'bslalg::TypeTraitUsesBslmaAllocator', which allows the trait
// 'bslma::UsesBslmaAllocator' to be declared using the (deprecated)
// 'BSLALG_DECLARE_NESTED_TRAITS' macro.  See the 'bslma_usesbslmaallocator'
// component for details of this trait.
//
///Usage
///-----
// No Usage example is provided since this component is deprecated.
