Reading, writing and manipulating text-based subtitle files.

:mod:`aeidon` is a Python package that provides classes and functions for
dealing with text-based subtitle files of many different formats. Functions
exist for reading and writing subtitle files as well as manipulating subtitle
data, i.e. positions (times or frames) and texts. Two examples of basic use
of the :mod:`aeidon` package follow below.

Converting a file from the SubRip format to the MicroDVD format::

    project = aeidon.Project()
    project.open_main("/path/to/file.srt", "utf_8")
    project.set_framerate(aeidon.framerates.FPS_23_976)
    project.save_main(aeidon.files.new(aeidon.formats.MICRODVD,
                                       "/path/to/file.sub",
                                       "utf_8"))

Making all subtitles in a file appear two seconds earlier::

    project = aeidon.Project()
    project.open_main("/path/to/file.srt", "utf_8")
    project.shift_positions(None, aeidon.as_seconds(-2))
    project.save_main()

:mod:`aeidon` handles positions as either times (as strings of form
``HH:MM:SS.SSS``), frames (as integers) or in some cases seconds (as floats).
All these can be used with functions that edit subtitle data regardless of what
the native position type of the file format used is.

:mod:`aeidon` handles two separate documents that comprise a project -- a main
and a translation document. These correspond to separate files, but the
subtitles are common since positions are shared.

:mod:`aeidon` includes an undo/redo-system. Any subtitle data-editing methods
of :class:`aeidon.Project` (ones marked with the :func:`aeidon.deco.revertable`
decorator) can be undone and redone. If using :mod:`aeidon` in a context where
reverting actions is never needed, greater flexibility can be achieved by
accessing the subtitles directly (via :attr:`aeidon.Project.subtitles`).
