+"""Allow bash-completion for argparse with argcomplete if installed.
+
+Needs argcomplete>=0.5.6 for python 3.2/3.3 (older versions fail
+to find the magic string, so _ARGCOMPLETE env. var is never set, and
+this does not need special code).
+
+Function try_argcomplete(parser) should be called directly before
+the call to ArgumentParser.parse_args().
+
+The filescompleter is what you normally would use on the positional
+arguments specification, in order to get "dirname/" after "dirn<TAB>"
+instead of the default "dirname ":
+
+   optparser.add_argument(Config._file_or_dir, nargs='*').completer=filescompleter
+
+Other, application specific, completers should go in the file
+doing the add_argument calls as they need to be specified as .completer
+attributes as well. (If argcomplete is not installed, the function the
+attribute points to will not be used).
+
+SPEEDUP
+=======
+
+The generic argcomplete script for bash-completion
+(/etc/bash_completion.d/python-argcomplete.sh)
+uses a python program to determine startup script generated by pip.
+You can speed up completion somewhat by changing this script to include
+  # PYTHON_ARGCOMPLETE_OK
+so the python-argcomplete-check-easy-install-script does not
+need to be called to find the entry point of the code and see if that is
+marked  with PYTHON_ARGCOMPLETE_OK.
+
+INSTALL/DEBUGGING
+=================
+
+To include this support in another application that has setup.py generated
+scripts:
+
+- Add the line:
+    # PYTHON_ARGCOMPLETE_OK
+  near the top of the main python entry point.
+
+- Include in the file calling parse_args():
+    from _argcomplete import try_argcomplete, filescompleter
+  Call try_argcomplete just before parse_args(), and optionally add
+  filescompleter to the positional arguments' add_argument().
+
+If things do not work right away:
+
+- Switch on argcomplete debugging with (also helpful when doing custom
+  completers):
+    export _ARC_DEBUG=1
+
+- Run:
+    python-argcomplete-check-easy-install-script $(which appname)
+    echo $?
+  will echo 0 if the magic line has been found, 1 if not.
+
+- Sometimes it helps to find early on errors using:
+    _ARGCOMPLETE=1 _ARC_DEBUG=1 appname
+  which should throw a KeyError: 'COMPLINE' (which is properly set by the
+  global argcomplete script).

+    """Assertion rewriting implementation.
+
+    The main entrypoint is to call .run() with an ast.Module instance,
+    this will then find all the assert statements and rewrite them to
+    provide intermediate values and a detailed assertion error.  See
+    http://pybites.blogspot.be/2011/07/behind-scenes-of-pytests-new-assertion.html
+    for an overview of how this works.
+
+    The entry point here is .run() which will iterate over all the
+    statements in an ast.Module and for each ast.Assert statement it
+    finds call .visit() with it.  Then .visit_Assert() takes over and
+    is responsible for creating new ast statements to replace the
+    original assert statement: it rewrites the test of an assertion
+    to provide intermediate values and replace it with an if statement
+    which raises an assertion error with a detailed explanation in
+    case the expression is false and calls pytest_assertion_pass hook
+    if expression is true.
+
+    For this .visit_Assert() uses the visitor pattern to visit all the
+    AST nodes of the ast.Assert.test field, each visit call returning
+    an AST node and the corresponding explanation string.  During this
+    state is kept in several instance attributes:
+
+    :statements: All the AST statements which will replace the assert
+       statement.
+
+    :variables: This is populated by .variable() with each variable
+       used by the statements so that they can all be set to None at
+       the end of the statements.
+
+    :variable_counter: Counter to create new unique variables needed
+       by statements.  Variables are created using .variable() and
+       have the form of "@py_assert0".
+
+    :expl_stmts: The AST statements which will be executed to get
+       data from the assertion.  This is the code which will construct
+       the detailed assertion message that is used in the AssertionError
+       or for the pytest_assertion_pass hook.
+
+    :explanation_specifiers: A dict filled by .explanation_param()
+       with %-formatting placeholders and their corresponding
+       expressions to use in the building of an assertion message.
+       This is used by .pop_format_context() to build a message.
+
+    :stack: A stack of the explanation_specifiers dicts maintained by
+       .push_format_context() and .pop_format_context() which allows
+       to build another %-formatted string while already building one.
+
+    :variables_overwrite: A dict filled with references to variables
+       that change value within an assert. This happens when a variable is
+       reassigned with the walrus operator
+
+    This state, except the variables_overwrite,  is reset on every new assert
+    statement visited and used by the other visitors.
