This header is part of the containers library.

Classes
list	doubly-linked list (class template)
Functions
operator==operator!=operator<operator<=operator>operator>=	lexicographically compares the values in the list (function template)
std::swap(std::list)	specializes the std::swap algorithm (function template)
