+       test defs: new function 'fatal_', for hard errors
+       Before this patch, the only way offered by tests/defs to
+       properly signal a hard error was the `framework_failure_'
+       function.  But the error message issued by that function,
+       as its name would suggest, refers to a set-up failure in the
+       testsuite, while hard errors can obviously also be due to
+       other reasons.  The best way to fix this inconsistency is to
+       introduce a new function with a more general error message.
+       Inspired by a recent similar change to Gnulib's tests/init.sh.
+       * tests/defs.in (fatal_): New function.
+       * tests/README (Section "Writing test cases" subsection "Do"):
+       Suggest the use of `fatal_', not of `framework_failure_', for
+       generic hard errors.  The latter should be reserved for "real"
+       set-up failures.

 +
 +      py-compile: '--' and non-option arguments terminate the option list
 +      * lib/py-compile: Any non-option argument, or the special `--'
 +      argument, now explicitly terminates the list of options.
 +      * tests/py-compile-option-terminate.test: New test.
 +      * tests/Makefile.am (TESTS): Update.
 +      * NEWS: Update.

 +
 +      py-compile: complain on unrecognized options
 +      * lib/py-compile: Complain on unrecognized options.  Don't be too
 +      lax in matching `--help' and `--version' options.
 +      * tests/py-compile-usage.test: Extend accordingly.
 +      * NEWS: Update.
 +
 +2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>
 +
 +      py-compile: normalize error and help messages
 +      * lib/py-compile: Now error messages do not begin with a capital
 +      letter, nor end with a period, as per GNU standards.  Prepend the
 +      error messages with the name of the script, not with its path.
 +      When an invalid usage is recognized, always display the customary
 +      message "Try `py-compile --help' ..." on a line of its own.
 +      ($me): New variable, containing the name of the
 +      program, i.e., `py-compile'.  Use it throughout.
 +      (usage_error): New function, used to display error messages about
 +      invalid usage.
 +      * tests/py-compile-usage.test: Extend and tighten accordingly.

 +
 +      python tests: add "unit tests" on py-compile
 +      * tests/py-compile-basic.test: New test.
 +      * tests/py-compile-basic2.test: New test.
 +      * tests/py-compile-basedir.test: Likewise.
 +      * tests/py-compile-destdir.test: Likewise.
 +      * tests/py-compile-env.test: Likewise.
 +      * tests/py-compile-usage.test: Likewise.
 +      * tests/Makefile.am (TESTS): Update.
 +      Tested with python 2.0.1, 2.4.6, 2.6.6, 2.7.1, and 3.1.3.

 +
 +      py-compile: the '--destdir' option now accepts a blank argument
 +      * lib/py-compile (Option parsing): Do not count an empty argument
 +      to `--destdir' or `--basedir' as a missing argument.
 +      * lib/python.am: Simplify accordingly, passing the `--destdir'
 +      option to py-compile unconditionally, even if `$(DESTDIR)' is
 +      empty.
 +      * NEWS: Update.
 +
 +2011-06-08  Stefano Lattarini  <stefano.lattarini@gmail.com>
 +
 +      python: run the 'py-compile' script with $(SHELL)
 +      * lib/python.am (install-%DIR%PYTHON): Run each instance of
 +      py-compile using $(SHELL).  Since we are at it, break overly
 +      long lines.
 +      (am__py_compile): New variable, to reduce code duplication.
