+/*! \file boost/algorithm/string/predicate.hpp
+    Defines string-related predicates. 
+    The predicates determine whether a substring is contained in the input string 
+    under various conditions: a string starts with the substring, ends with the 
+    substring, simply contains the substring or if both strings are equal.
+    Additionaly the algorithm \c all() checks all elements of a container to satisfy a 
+    condition.
+
+    All predicates provide the strong exception guarantee.

+    Traits defined in this header are used by various algorithms to achieve

+    Traits provide fail-safe defaults. If a container supports some of these

+    For lacking compilers, it is possible of define an override for a specific tester
+    function.
+
+    Due to a language restriction, it is not currently possible to define specializations for
+    stl containers without including the corresponding header. To decrease the overhead
+    needed by this inclusion, user can selectively include a specialization
+    header for a specific container. They are located in boost/algorithm/string/stl

+/*! \file
+    Defines trim_all algorithms.
+    
+    Just like \c trim, \c trim_all removes all trailing and leading spaces from a 
+    sequence (string). In addition, spaces in the middle of the sequence are truncated
+    to just one character. Space is recognized using given locales.
+
+    \c trim_fill acts as trim_all, but the spaces in the middle are replaces with 
+    a user-define sequence of character.
+
+    Parametric (\c _if) variants use a predicate (functor) to select which characters
+    are to be trimmed.. 
+    Functions take a selection predicate as a parameter, which is used to determine 
+    whether a character is a space. Common predicates are provided in classification.hpp header.
