-class Configurations(object):
-    """
-        This class helps to manage toolset configurations. Each configuration
-        has a unique ID and one or more parameters. A typical example of a unique ID
-        is a condition generated by 'common.check-init-parameters' rule. Other kinds
-        of IDs can be used. Parameters may include any details about the configuration
-        like 'command', 'path', etc.
-
-        A toolset configuration may be in one of the following states:
-
-        - registered
-              Configuration has been registered (e.g. by autodetection code) but has
-              not yet been marked as used, i.e. 'toolset.using' rule has not yet been
-              called for it.
-          - used
-              Once called 'toolset.using' rule marks the configuration as 'used'.
-
-        The main difference between the states above is that while a configuration is
-        'registered' its options can be freely changed. This is useful in particular
-        for autodetection code - all detected configurations may be safely overwritten

-        #   Several ideas pop to mind on how to fix this:
-        #     * One way would be to separate the commands using the ; shell
-        #       command separator. This seems like the quickest possible
-        #       solution but I do not know whether this would break code on any
-        #       platforms I I have no access to.
-        #     * Another would be to not use the terminating $(nl) but that would
-        #       require updating all the using code so it does not simply
-        #       prepend this variable to its own commands.
-        #     * I guess the cleanest solution would be to update Boost Jam to
-        #       allow explicitly specifying \n & \r characters in its scripts
-        #       instead of always relying only on the 'current OS native newline
-        #       sequence'.
-        #
-        #   Some code found to depend on this behaviour:
-        #     * This Boost Build module.
-        #         * __test__ rule.
-        #         * path-variable-setting-command rule.
-        #     * python.jam toolset.
-        #     * xsltproc.jam toolset.
-        #     * fop.jam toolset.
