# Boost library support module.
#
# This module allows to use the boost library from boost-build projects. The
# location of a boost source tree or the path to a pre-built version of the
# library can be configured from either site-config.jam or user-config.jam. If
# no location is configured the module looks for a BOOST_ROOT environment
# variable, which should point to a boost source tree. As a last resort it tries
# to use pre-built libraries from the standard search path of the compiler.
#
# If the location to a source tree is known, the module can be configured from
# the *-config.jam files:
#
# using boost : 1.35 : <root>/path-to-boost-root ;
#
# If the location to a pre-built version is known:
#
# using boost : 1.34
# : <include>/usr/local/include/boost_1_34
# <library>/usr/local/lib
# ;
#
# It is legal to configure more than one boost library version in the config
# files. The version identifier is used to disambiguate between them. The first
# configured version becomes the default.
#
# To use a boost library you need to put a 'use' statement into your Jamfile:
#
# import boost ;
#
# boost.use-project 1.35 ;
#
# If you do not care about a specific version you just can omit the version
# part, in which case the default is picked up:
#
# boost.use-project ;
#
# The library can be referenced with the project identifier '/boost'. To
# reference the program_options you would specify:
#
# exe myexe : mysrc.cpp : <library>/boost//program_options ;
#
# Note that the requirements are automatically transformed into suitable tags to
# find the correct pre-built library.

# This can either be a boost source tree or pre-built libraries. The 'version'
# parameter must be a valid boost version number, e.g. 1.35, if specifying a
# pre-built version with versioned layout. It may be a symbolic name, e.g.
# 'trunk' if specifying a source tree. The options are specified as named
# parameters (like properties). The following paramters are available:
#
# <root>/path-to-boost-root : Specify a source tree.
# <include>/path-to-include : The include directory to search.
# <library>/path-to-library : The library directory to search.
# <layout>system or <layout>versioned : Built library layout.
# <build-id>my_build_id : The custom build id to use.
