-# 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).
