+
+//! The class template slist is an intrusive container, that encapsulates
+//! a singly-linked list. You can use such a list to squeeze the last bit
+//! of performance from your application. Unfortunately, the little gains
+//! come with some huge drawbacks. A lot of member functions can't be
+//! implemented as efficiently as for standard containers. To overcome
+//! this limitation some other member functions with rather unusual semantics
+//! have to be introduced.
+//!
+//! The template parameter \c T is the type to be managed by the container.
+//! The user can specify additional options and if no options are provided
+//! default options are used.
+//!
+//! The container supports the following options:
+//! \c base_hook<>/member_hook<>/value_traits<>,
+//! \c constant_time_size<>, \c size_type<>,
+//! \c linear<> and \c cache_last<>.
+//!
+//! The iterators of slist are forward iterators. slist provides a static
+//! function called "previous" to compute the previous iterator of a given iterator.
+//! This function has linear complexity. To improve the usability esp. with
+//! the '*_after' functions, ++end() == begin() and previous(begin()) == end()
+//! are defined. An new special function "before_begin()" is defined, which returns
+//! an iterator that points one less the beginning of the list: ++before_begin() == begin()
