    Converts any URLs in text into clickable links.

    Works on http://, https://, www. links, and also on links ending in one of

    the original seven gTLDs (.com, .edu, .gov, .int, .mil, .net, and .org) or

    a two-letter ccTLD. Links can have trailing punctuation (periods, commas,

    close-parens) and leading punctuation (opening parens) and it'll still do

    the right thing.

Converts URLs in text into clickable links.

This template tag works on several kinds of links:

- links prefixed with ``http://``, ``https://``, or ``www.``. For example,

  ``http://goo.gl/aia1t`` will get converted but ``goo.gl/aia1t`` won't.

- domain-only links ending in one of the original top level domains

  (``.com``, ``.edu``, ``.gov``, ``.int``, ``.mil``, ``.net``, and

  ``.org``). For example, ``djangoproject.com`` also gets converted.

- domain-only links ending in a dot followed by two letters. This covers

  most country codes. For example, ``djangocon.eu`` still gets converted.

It also supports domain-only links ending in one of the original top level
