+# This module implements regression testing framework. It declares a number of
+# main target rules which perform some action and, if the results are OK,
+# creates an output file.
+#
+# The exact list of rules is:
+# 'compile'       -- creates .test file if compilation of sources was
+#                    successful.
+# 'compile-fail'  -- creates .test file if compilation of sources failed.
+# 'run'           -- creates .test file is running of executable produced from
+#                    sources was successful. Also leaves behind .output file
+#                    with the output from program run.
+# 'run-fail'      -- same as above, but .test file is created if running fails.
+#
+# In all cases, presence of .test file is an indication that the test passed.
+# For more convenient reporting, you might want to use C++ Boost regression
+# testing utilities (see http://www.boost.org/more/regression.html).
+#
+# For historical reason, a 'unit-test' rule is available which has the same
+# syntax as 'exe' and behaves just like 'run'.
+
+# Things to do:
+#  - Teach compiler_status handle Jamfile.v2.
+# Notes:
+#  - <no-warn> is not implemented, since it is Como-specific, and it is not
+#    clear how to implement it
+#  - std::locale-support is not implemented (it is used in one test).
