+# Initialize a specific toolset version configuration. As the result, path to
+# compiler and, possible, program names are set up, and will be used when that
+# version of compiler is requested. For example, you might have:
+#
+#    using msvc : 6.5 : cl.exe ;
+#    using msvc : 7.0 : Y:/foo/bar/cl.exe ;
+#
+# The version parameter may be ommited:
+#
+#    using msvc : : Z:/foo/bar/cl.exe ;
+#
+# The following keywords have special meanings when specified as versions:
+#   - all     - all detected but not yet used versions will be marked as used
+#               with their default options.
+#   - default - this is an equivalent to an empty version.
+#
+# Depending on a supplied version, detected configurations and presence 'cl.exe'
+# in the path different results may be achieved. The following table describes
+# the possible scenarios:
+#
+#                                      Nothing            "x.y"
+# Passed   Nothing       "x.y"         detected,          detected,
+# version  detected      detected      cl.exe in path     cl.exe in path
+#
+# default  Error         Use "x.y"     Create "default"   Use "x.y"
+# all      None          Use all       None               Use all
+# x.y      -             Use "x.y"     -                  Use "x.y"
+# a.b      Error         Error         Create "a.b"       Create "a.b"
+#
+# "x.y" - refers to a detected version;
+# "a.b" - refers to an undetected version.
