+# alias lib : helpers xml_parser ;

+# alias platform-src : win.cpp : <os>NT ;
+# alias platform-src : linux.cpp : <os>LINUX ;
+# exe main : main.cpp platform-src ;
+#
+# Lastly, it's possible to create local alias for some target, with different
+# properties::
+#
+# alias big_lib : : @/external_project/big_lib/<link>static ;

+
+# 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 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.

+# 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'.
