+[section:v1 Version 1]
+
+The Filesystem Library was designed and implemented by Beman Dawes. The original `directory_iterator` and `filesystem_error` classes
+were based on prior work from Dietmar Kühl, as modified by Jan Langer. Thomas Witt was a particular help in later stages of initial
+development. Peter Dimov and Rob Stewart made many useful suggestions and comments over a long period of time. Howard Hinnant helped
+with internationalization issues.
+
+Key [link filesystem.design.requirements design requirements] and [link filesystem.design.realities design realities] were developed
+during extensive discussions on the Boost mailing list, followed by comments on the initial implementation. Numerous helpful comments
+were then received during the Formal Review. Participants included:

+A lengthy discussion on the C++ committee's library reflector illuminated the "illusion of portability" problem, particularly in
+postings by PJ Plauger and Pete Becker.
+
+Walter Landry provided much help illuminating symbolic link use cases for version 1.31.0.
+
+[endsect]
+
+[section:v2 Version 2]
+
+So many people have contributed comments and bug reports that it isn't any longer possible to acknowledge them individually. That said,
+Peter Dimov and Rob Stewart need to be specially thanked for their many constructive criticisms and suggestions. Terence Wilson and
+Chris Frey contributed timing programs which helped illuminate performance issues.
+
+[endsect]
+
+[section:v3 Version 3]
+
+Peter Dimov suggested the idea of a single path class that could cope with multiple character types and encodings rather than
+a `basic_path` class template. That idea was the basis for the Version 3 redesign. Walter Landry contributed both the design
+and implementation of the `copy_any`, `copy_directory`, `copy_symlink`, and `read_symlink` functions.
+
+Thanks for comments from Robert Stewart, Zach Laine, Peter Dimov, Gregory Peele, Scott McMurray, John Bytheway, Jeff Flinn,
+Jeffery Bosboom.

+[section:cautions Cautions]
+
+After reading the tutorial you can dive right into simple, script-like programs using
+the Filesystem Library! Before doing any serious work, however, there a few cautions to be aware of.
+
+[section:fs_races Effects and Postconditions not guaranteed in the presence of race-conditions]
+
+Filesystem function specifications follow the C++ Standard Library form, specifying behavior in terms of
+effects and postconditions. If a [link filesystem.reference.race_condition race-condition] exists,
+a function's postconditions may no longer be true by the time the function returns to the
+caller.
+
+The state of files and directories is often globally shared, and thus may be changed unexpectedly
+by other threads, processes, or even other computers having network access to the filesystem. As an
+example of the difficulties this can cause, note that the following asserts may fail:
+
+```
+assert(exists("foo") == exists("foo")); /*< This will fail if a non-existent "foo" comes into existence, or an
+                                            existent "foo" is removed, between the first and second call to `exists()`.
+                                            This could happen if, during the execution of the example code, another thread,
+                                            process, or computer is also performing operations in the same directory. */
+
+remove_all("foo");
+assert(!exists("foo")); /*< This will fail if between the call to `remove_all()` and the call to
+                            `exists()` a new file or directory named "foo" is created by another
+                            thread, process, or computer. */
+
+assert(is_directory("foo") == is_directory("foo")); /*< This will fail if another thread, process, or computer removes an
+                                                        existing file "foo" and then creates a directory named "foo", between the
+                                                        example code's two calls to `is_directory()`. */
+```
+
+[endsect]
+
+[section:exceptions Exceptions]
+
+Unless otherwise specified, Boost.Filesystem functions throw
+[link filesystem.reference.basic_filesystem_error-constructors `basic_filesystem_error`]
+exceptions to report failures such as I/O errors. Implementations may also use C++ Standard Library
+functions which can throw `std::bad_alloc` exceptions to report memory allocation errors. These exceptions
+may be thrown even though the error condition leading to the exception is not explicitly specified in
+the function's "Throws" paragraph.
+
+Nominally non-throwing versions are provided for [link filesystem.reference.operational-functions operational functions]
+that access the external file system, since these are often used in contexts where error codes may be
+the preferred way to report an error. Even the nominally non-throwing versions of functions will throw
+`std::bad_alloc` exceptions to report memory allocation errors. However, functions marked `noexcept` never
+throw exceptions.
