Hi,

I was wondering if we can add other categories to the library catalog 
(http://www.boost.org/users/history/version_1_47_0.html).

Here is a proposal

Best,
Vicente

Domain Specific

     crc - Cyclic Redundancy Code, from Daryle Walker.
     units - Zero-overhead dimensional analysis and unit/quantity 
manipulation and conversion, from Matthias Schabel and Steven Watanabe.
     uuid - A universally unique identifier, from Andy Tompkins.

Idioms

     base-from-member - Idiom to initialize a base class with a member, 
from Daryle Walker.
     compressed_pair - Empty member optimization, from John Maddock, 
Howard Hinnant, et al.

Language Emulation: these are libraries are emulating a missing language 
feature

     exception - A library for transporting of arbitrary data in 
exception objects, and transporting of exceptions between threads 
(N2179), from Emil Dotchevski.
     move - Portable move semantics for C++03 and C++1 compilers, from 
Ion Gaztañaga
     scope_exit - Execute arbitrary code at scope exit, from Alexander 
Nasonov.
     typeof - Typeof operator emulation, from Arkadiy Vertleyb and Peder 
Holt.

Patterns: libraries that implement a known pattern

     flyweight - Design pattern to manage large quantities of highly 
redundant objects, from Joaquín M López Muñoz.
     signals - managed signals & slots callback implementation, from 
Doug Gregor.
     signals2 - managed signals & slots callback implementation 
(thread-safe version 2), from Frank Mori Hess.

State Machines

     meta state machine - High-performance expressive UML 2.0 finite 
state machines, from Christophe Henry.
     statechart - Arbitrarily complex finite state machines can be 
implemented in easily readable and maintainable C++ code, from Andreas 
Huber.

System: libraries that are close to the underlying system

     chrono - Useful time utilities, from Howard Hinnant, Beman Dawes, 
Vicente J. Botet Escribá.
     date_time - Date-Time library from Jeff Garland.
     filesystem - Portable paths, iteration over directories, and other 
useful filesystem operations, from Beman Dawes.
     system - Operating system support, including the diagnostics 
support that will be part of the C++0x standard library, from Beman Dawes.

I would add also the following to exixting categories
Data structures

     optional - Discriminated-union wrapper for optional values, from 
Fernando Cacciola.
     tribool - 3-state boolean type library, from Doug Gregor.

I have no suggestion for the following, so we can maintain them in
Miscellaneous

     conversion - Polymorphic and lexical casts, from Dave Abrahams and 
Kevlin Henney.
     swap - Enhanced generic swap function, from Joseph Gauterin.
     timer - Event timer, progress timer, and progress display classes, 
from Beman Dawes.
     TR1 - An implementation of the Technical Report on C++ Library 
Extensions, using other Boost libraries as a basis, from John Maddock.
     utility - Class noncopyable plus checked_delete(), 
checked_array_delete(), next(),  prior() function templates, plus 
base-from-member idiom, from Dave Abrahams and others.
     value_initialized - Wrapper for uniform-syntax value 
initialization, from Fernando Cacciola, based on the original idea of 
David Abrahams.

The following libraries are already in another category

     lexical_cast -  General literal text conversions, such as an int 
represented as a string, or vice-versa, from Kevlin Henney.
     numeric/conversion - Optimized Policy-based Numeric Conversions, 
from Fernando Cacciola.
     program_options - Access to configuration data given on command 
line, in config files and other sources, from Vladimir Prus.
