-# Manages 'generators' --- objects which can do transformation between different
-# target types and contain algorithm for finding transformation from sources to
-# targets.
-#
-# The main entry point to this module is generators.construct rule. It is given
-# a list of source targets, desired target type and a set of properties. It
-# starts by selecting 'viable generators', which have any chances of producing
-# the desired target type with the required properties. Generators are ranked
-# and a set of the most specific ones is selected.
-#
-# The most specific generators have their 'run' methods called, with the
-# properties and list of sources. Each one selects a target which can be
-# directly consumed, and tries to convert the remaining ones to the types it can
-# consume. This is done by recursively calling 'construct' with all consumable
-# types.
-#
-# If the generator has collected all the targets it needs, it creates targets
-# corresponding to result, and returns it. When all generators have been run,
-# results of one of them are selected and returned as a result.
-#
-# It is quite possible for 'construct' to return more targets that it was asked
-# for. For example, if it were asked to generate a target of type EXE, but the
-# only found generator produces both EXE and TDS (file with debug) information.
-# The extra target will be returned.
-#
-# Likewise, when generator tries to convert sources to consumable types, it can
-# get more targets that it was asked for. The question is what to do with extra
-# targets. Boost.Build attempts to convert them to requested types, and attempts
-# that as early as possible. Specifically, this is done after invoking each
-# generator. TODO: An example is needed to document the rationale for trying
-# extra target conversion at that point.
-#
-# In order for the system to be able to use a specific generator instance 'when
-# needed', the instance needs to be registered with the system using
-# generators.register() or one of its related rules. Unregistered generators may
-# only be run explicitly and will not be considered by Boost.Build when when
-# converting between given target types.

-# Manages 'generators' --- objects which can do transformation between different
-# target types and contain algorithm for finding transformation from sources
-# to targets.
-#
-# The main entry point to this module is generators.construct rule. It is given
-# a list of source targets, desired target type and a set of properties.
-# It starts by selecting 'viable generators', which have any chances of producing
-# the desired target type with the required properties. Generators are ranked and
-# a set of most specific ones is selected.
-#
-# The most specific generators have their 'run' methods called, with the properties
-# and list of sources. Each one selects target which can be directly consumed, and
-# tries to convert the remaining ones to the types it can consume. This is done
-# by recursively calling 'construct' with all consumable types.
-#
-# If the generator has collected all the targets it needs, it creates targets
-# corresponding to result, and returns it. When all generators have been run,
-# results of one of them are selected and returned as result.
-#
-# It's quite possible that 'construct' returns more targets that it was asked for.
-# For example, it was asked to target type EXE, but the only found generators produces
-# both EXE and TDS (file with debug) information. The extra target will be returned.
-#
-# Likewise, when generator tries to convert sources to consumable types, it can get
-# more targets that it was asked for. The question is what to do with extra targets.
-# Boost.Build attempts to convert them to requested types, and attempts as early as
-# possible. Specifically, this is done after invoking each generator. (Later I'll
-# document the rationale for trying extra target conversion at that point).
-#
-# That early conversion is not always desirable. Suppose a generator got a source of
-# type Y and must consume one target of type X_1 and one target of type X_2.
-# When converting Y to X_1 extra target of type Y_2 is created. We should not try to
-# convert it to type X_1, because if we do so, the generator will get two targets
-# of type X_1, and will be at loss as to which one to use. Because of that, the
-# 'construct' rule has a parameter, telling if multiple targets can be returned. If
-# the parameter is false, conversion of extra targets is not performed.

-# Implements project representation and loading. Each project is represented by:
-# - a module where all the Jamfile content live.
-# - an instance of 'project-attributes' class.
-# (given a module name, can be obtained using the 'attributes' rule)
-# - an instance of 'project-target' class (from targets.jam)
-# (given a module name, can be obtained using the 'target' rule)
-#
-# Typically, projects are created as result of loading a Jamfile, which is done
-# by rules 'load' and 'initialize', below. First, module for Jamfile is loaded
-# and new project-attributes instance is created. Some rules necessary for
-# project are added to the module (see 'project-rules' module) at the bottom of
-# this file. Default project attributes are set (inheriting attributes of parent
-# project, if it exists). After that the Jamfile is read. It can declare its own
-# attributes using the 'project' rule which will be combined with any already
-# set attributes.
-#
-# The 'project' rule can also declare a project id which will be associated with
-# the project module.
-#
-# There can also be 'standalone' projects. They are created by calling
-# 'initialize' on an arbitrary module and not specifying their location. After
-# the call, the module can call the 'project' rule, declare main targets and
-# behave as a regular project except that, since it is not associated with any
-# location, it should not declare targets that are not prebuilt.
-#
-# The list of all loaded Jamfile is stored in the .project-locations variable.
-# It is possible to obtain a module name for a location using the 'module-name'
-# rule. Standalone projects are not recorded and can only be referenced using
-# their project id.

-# Implements project representation and loading.
-# Each project is represented by
-# - a module where all the Jamfile content live.
-# - an instance of 'project-attributes' class.
-# (given module name, can be obtained by 'attributes' rule)
-# - an instance of 'project-target' class (from targets.jam)
-# (given a module name, can be obtained by 'target' rule)
-#
-# Typically, projects are created as result of loading Jamfile, which is
-# do by rules 'load' and 'initialize', below. First, module for Jamfile
-# is loaded and new project-attributes instance is created. Some rules
-# necessary for project are added to the module (see 'project-rules' module)
-# at the bottom of this file.
-# Default project attributes are set (inheriting attributes of parent project, if
-# it exists). After that, Jamfile is read. It can declare its own attributes,
-# via 'project' rule, which will be combined with already set attributes.
-#
-#
-# The 'project' rule can also declare project id, which will be associated with
-# the project module.
-#
-# There can also be 'standalone' projects. They are created by calling 'initialize'
-# on arbitrary module, and not specifying location. After the call, the module can
-# call 'project' rule, declare main target and behave as regular projects. However,
-# since it's not associated with any location, it's better declare only prebuilt
-# targets.
-#
-# The list of all loaded Jamfile is stored in variable .project-locations. It's possible
-# to obtain module name for a location using 'module-name' rule. The standalone projects
-# are not recorded, the only way to use them is by project id.

-# Implements scanners: objects that compute implicit dependencies for
-# files, such as includes in C++.
-#
-# Scanner has a regular expression used to find dependencies, some
-# data needed to interpret those dependencies (for example, include
-# paths), and a code which actually established needed relationship
-# between actual jam targets.
-#
-# Scanner objects are created by actions, when they try to actualize
-# virtual targets, passed to 'virtual-target.actualize' method and are
-# then associated with actual targets. It is possible to use
-# several scanners for a virtual-target. For example, a single source
-# might be used by to compile actions, with different include paths.
-# In this case, two different actual targets will be created, each
-# having scanner of its own.
-#
-# Typically, scanners are created from target type and action's
-# properties, using the rule 'get' in this module. Directly creating
-# scanners is not recommended, because it might create many equvivalent
-# but different instances, and lead in unneeded duplication of
-# actual targets. However, actions can also create scanners in a special

-# Implements scanners: objects that compute implicit dependencies for
-# files, such as includes in C++.
-#
-# Scanner has a regular expression used to find dependencies, some
-# data needed to interpret those dependencies (for example, include
-# paths), and a code which actually established needed relationship
-# between actual jam targets.
-#
-# Scanner objects are created by actions, when they try to actualize
-# virtual targets, passed to 'virtual-target.actualize' method and are
-# then associated with actual targets. It is possible to use
-# several scanners for a virtual-target. For example, a single source
-# might be used by to compile actions, with different include paths.
-# In this case, two different actual targets will be created, each
-# having scanner of its own.
-#
-# Typically, scanners are created from target type and action's
-# properties, using the rule 'get' in this module. Directly creating
-# scanners is not recommended, because it might create many equvivalent
-# but different instances, and lead in unneeded duplication of
-# actual targets. However, actions can also create scanners in a special
-# way, instead of relying on just target type.

-# Supports 'abstract' targets, which are targets explicitly defined in a
-# Jamfile.
-#
-# Abstract targets are represented by classes derived from 'abstract-target'
-# class. The first abstract target is 'project-target', which is created for
-# each Jamfile, and can be obtained by the 'target' rule in the Jamfile's module
-# (see project.jam).
-#
-# Project targets keep a list of 'main-target' instances. A main target is what
-# the user explicitly defines in a Jamfile. It is possible to have several
-# definitions for a main target, for example to have different lists of sources
-# for different platforms. So, main targets keep a list of alternatives.
-#
-# Each alternative is an instance of 'abstract-target'. When a main target
-# subvariant is defined by some rule, that rule will decide what class to use,
-# create an instance of that class and add it to the list of alternatives for
-# the main target.
-#
-# Rules supplied by the build system will use only targets derived from
-# 'basic-target' class, which will provide some default behaviour. There will be
-# different classes derived from it such as 'make-target', created by the 'make'
-# rule, and 'typed-target', created by rules such as 'exe' and 'lib'.

-# Supports 'abstract' targets, which are targets explicitly defined in Jamfile.
-#
-# Abstract targets are represented by classes derived from 'AbstractTarget' class.
-# The first abstract target is 'project_target', which is created for each
-# Jamfile, and can be obtained by the 'target' rule in the Jamfile's module.
-# (see project.jam).
-#
-# Project targets keep a list of 'MainTarget' instances.
-# A main target is what the user explicitly defines in a Jamfile. It is
-# possible to have several definitions for a main target, for example to have
-# different lists of sources for different platforms. So, main targets
-# keep a list of alternatives.
-#
-# Each alternative is an instance of 'AbstractTarget'. When a main target
-# subvariant is defined by some rule, that rule will decide what class to
-# use, create an instance of that class and add it to the list of alternatives
-# for the main target.
-#
-# Rules supplied by the build system will use only targets derived
-# from 'BasicTarget' class, which will provide some default behaviour.
-# There will be two classes derived from it, 'make-target', created by the
-# 'make' rule, and 'TypedTarget', created by rules such as 'exe' and 'dll'.
