:mod:`mhlib` --- Access to MH mailboxes
=======================================

.. module:: mhlib
   :synopsis: Manipulate MH mailboxes from Python.
   :deprecated:
   
.. deprecated:: 2.6
    The :mod:`mhlib` module has been removed in Python 3.0. Use the
    :mod:`mailbox` instead.

.. sectionauthor:: Skip Montanaro <skip@pobox.com>

The :mod:`mhlib` module provides a Python interface to MH folders and their
contents.

The module contains three basic classes, :class:`MH`, which represents a
particular collection of folders, :class:`Folder`, which represents a single
folder, and :class:`Message`, which represents a single message.


.. class:: MH([path[, profile]])

   :class:`MH` represents a collection of MH folders.


.. class:: Folder(mh, name)

   The :class:`Folder` class represents a single folder and its messages.


.. class:: Message(folder, number[, name])

   :class:`Message` objects represent individual messages in a folder.  The Message
   class is derived from :class:`mimetools.Message`.

.. method:: MH.deletefolder(name)

   Delete a folder -- must have no subfolders.


.. method:: MH.openfolder(name)

   Return a new open folder object.

.. method:: Folder.getfullname()

   Return the folder's full pathname.


.. method:: Folder.getsequencesfilename()

   Return the full pathname of the folder's sequences file.


.. method:: Folder.getmessagefilename(n)

   Return the full pathname of message *n* of the folder.


.. method:: Folder.listmessages()

   Return a list of messages in the folder (as numbers).


.. method:: Folder.getcurrent()

   Return the current message number.


.. method:: Folder.setcurrent(n)

   Set the current message number to *n*.


.. method:: Folder.parsesequence(seq)
