-#  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.
