        ====================
        
        The MDA-XDRLIB package is a mostly vendored implementation of the
        cpython xdrlib module as released in cpython version 3.10.8.
        
        As such the package is released under the same licensing as the
        original code, as detailed below.
        
        To satisfy clause 3 of the PSF License Version 2, a list of changes
        introduced is also shipped alongside the code under `CHANGES`.

        A. HISTORY OF THE SOFTWARE
        ==========================
        
        Python was created in the early 1990s by Guido van Rossum at Stichting
        Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands
        as a successor of a language called ABC.  Guido remains Python's
        principal author, although it includes many contributions from others.
        
        In 1995, Guido continued his work on Python at the Corporation for
        National Research Initiatives (CNRI, see https://www.cnri.reston.va.us)
        in Reston, Virginia where he released several versions of the
        software.
        
        In May 2000, Guido and the Python core development team moved to
        BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
        year, the PythonLabs team moved to Digital Creations, which became
        Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
        https://www.python.org/psf/) was formed, a non-profit organization
        created specifically to own Python-related Intellectual Property.
        Zope Corporation was a sponsoring member of the PSF.
        
        All Python releases are Open Source (see https://opensource.org for
        the Open Source Definition).  Historically, most, but not all, Python
        releases have also been GPL-compatible; the table below summarizes
        the various releases.

        Footnotes:
        
        (1) GPL-compatible doesn't mean that we're distributing Python under
            the GPL.  All Python licenses, unlike the GPL, let you distribute
            a modified version without making your changes open source.  The
            GPL-compatible licenses make it possible to combine Python with
            other software that is released under the GPL; the others don't.
        
        (2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
            because its license has a choice of law clause.  According to
            CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
            is "not incompatible" with the GPL.
        
        Thanks to the many outside volunteers who have worked under Guido's
        direction to make these releases possible.

# mda_xdrlib

A stand-alone XDRLIB module extracted from cpython 3.10.8


## Why does this package exist?

The xdrlib package has historically been a feature of the core python library.
However, as of Python 3.11, the module was deemed to no longer be widely used
and has been deprecated, with a target removal version of Python 3.13.

Several of the MDAnalysis projects rely on the xdrlib module for their
functionality, specifically for parsing GROMACS TPR and EDR files. To
avoid a need to vendor in the xdrlib functionality in multiple projects,
we take the approach of creating this stand-alone module which contains
the python 3.10.8 xdrlib code and its relevant tests.


## Changes from the cpython implementation

The majority of this code is copied from the 3.10.8 release of cpython.
Any modifications of the code are mostly cosmetic. A full copy of these
modifications can found in the [CHANGES](./CHANGES) file.


## License

Being taken from the cpython 3.10.8 release, the code within this repository
falls under the Python Software Foundation License Version 2. Any
documentation is also dual licensed with both the PSF License Version 2 and
the zero-clause BSD license. More information can be found in
