+# Configurations
+#
+# The following 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. explicitly or by auto-detection
+# 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
+# by user code.
