+Description: =========
+        Blessings
+        =========
+        
+        Coding with Blessings looks like this... ::
+        
+            from blessings import Terminal
+        
+            t = Terminal()
+        
+            print t.bold('Hi there!')
+            print t.bold_red_on_bright_green('It hurts my eyes!')
+        
+            with t.location(0, t.height - 1):
+                print 'This is at the bottom.'
+        
+        Or, for byte-level control, you can drop down and play with raw terminal
+        capabilities::
+        
+            print '{t.bold}All your {t.red}bold and red base{t.normal}'.format(t=t)
+            print t.wingo(2)
+        
+        The Pitch
+        =========
+        
+        Blessings lifts several of curses_' limiting assumptions, and it makes your
+        code pretty, too:
+        
+        * Use styles, color, and maybe a little positioning without clearing the whole
+          screen first.
+        * Leave more than one screenful of scrollback in the buffer after your program
+          exits, like a well-behaved command-line app should.
+        * Get rid of all those noisy, C-like calls to ``tigetstr`` and ``tparm``, so
+          your code doesn't get crowded out by terminal bookkeeping.
+        * Act intelligently when somebody redirects your output to a file, omitting the
+          terminal control codes the user doesn't want to see (optional).

+        .. _curses: http://docs.python.org/library/curses.html
+        
+        Before And After
+        ----------------
+        
+        Without Blessings, this is how you'd print some underlined text at the bottom
+        of the screen::
+        
+            from curses import tigetstr, setupterm, tparm
+            from fcntl import ioctl
+            from os import isatty
+            import struct
+            import sys
+            from termios import TIOCGWINSZ
+        
+            # If we want to tolerate having our output piped to other commands or
+            # files without crashing, we need to do all this branching:
+            if hasattr(sys.stdout, 'fileno') and isatty(sys.stdout.fileno()):
+                setupterm()
+                sc = tigetstr('sc')
+                cup = tigetstr('cup')
+                rc = tigetstr('rc')
+                underline = tigetstr('smul')
+                normal = tigetstr('sgr0')
+            else:
+                sc = cup = rc = underline = normal = ''
+            print sc  # Save cursor position.
+            if cup:
+                # tigetnum('lines') doesn't always update promptly, hence this:
+                height = struct.unpack('hhhh', ioctl(0, TIOCGWINSZ, '\000' * 8))[0]
+                print tparm(cup, height - 1, 0)  # Move cursor to bottom.
+            print 'This is {under}underlined{normal}!'.format(under=underline,
+                                                              normal=normal)
+            print rc  # Restore cursor position.
+        
+        Phew! That was long and full of incomprehensible trash! Let's try it again,
+        this time with Blessings::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            with term.location(0, term.height - 1):
+                print 'This is', term.underline('pretty!')
+        
+        Much better.
+        
+        What It Provides
+        ================
+        
+        Blessings provides just one top-level object: ``Terminal``. Instantiating a
+        ``Terminal`` figures out whether you're on a terminal at all and, if so, does
+        any necessary terminal setup. After that, you can proceed to ask it all sorts
+        of things about the terminal. Terminal terminal terminal.
+        
+        Simple Formatting
+        -----------------
+        
+        Lots of handy formatting codes ("capabilities" in low-level parlance) are
+        available as attributes on a ``Terminal``. For example::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            print 'I am ' + term.bold + 'bold' + term.normal + '!'
+        
+        You can also use them as wrappers so you don't have to say ``normal``
+        afterward::
+        
+            print 'I am', term.bold('bold') + '!'
+        
+        Or, if you want fine-grained control while maintaining some semblance of
+        brevity, you can combine it with Python's string formatting, which makes
+        attributes easy to access::
+        
+            print 'All your {t.red}base {t.underline}are belong to us{t.normal}'.format(t=term)
+        
+        Simple capabilities of interest include...
+        
+        * ``bold``
+        * ``reverse``
+        * ``underline``
+        * ``no_underline`` (which turns off underlining)
+        * ``blink``
+        * ``normal`` (which turns off everything, even colors)
+        * ``clear_eol`` (clear to the end of the line)
+        * ``clear_bol`` (clear to beginning of line)
+        * ``clear_eos`` (clear to end of screen)
+        
+        Here are a few more which are less likely to work on all terminals:
+        
+        * ``dim``
+        * ``italic`` and ``no_italic``
+        * ``shadow`` and ``no_shadow``
+        * ``standout`` and ``no_standout``
+        * ``subscript`` and ``no_subscript``
+        * ``superscript`` and ``no_superscript``
+        * ``flash`` (which flashes the screen once)
+        
+        Note that, while the inverse of ``underline`` is ``no_underline``, the only way
+        to turn off ``bold`` or ``reverse`` is ``normal``, which also cancels any
+        custom colors. This is because there's no way to tell the terminal to undo
+        certain pieces of formatting, even at the lowest level.
+        
+        You might notice that the above aren't the typical incomprehensible terminfo
+        capability names; we alias a few of the harder-to-remember ones for
+        readability. However, you aren't limited to these: you can reference any
+        string-returning capability listed on the `terminfo man page`_ by the name
+        under the "Cap-name" column: for example, ``term.rum``.
+        
+        .. _`terminfo man page`: http://www.manpagez.com/man/5/terminfo/
+        
+        Color
+        -----
+        
+        16 colors, both foreground and background, are available as easy-to-remember
+        attributes::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            print term.red + term.on_green + 'Red on green? Ick!' + term.normal
+            print term.bright_red + term.on_bright_blue + 'This is even worse!' + term.normal
+        
+        You can also call them as wrappers, which sets everything back to normal at the
+        end::
+        
+            print term.red_on_green('Red on green? Ick!')
+            print term.yellow('I can barely see it.')
+        
+        The available colors are...
+        
+        * ``black``
+        * ``red``
+        * ``green``
+        * ``yellow``
+        * ``blue``
+        * ``magenta``
+        * ``cyan``
+        * ``white``
+        
+        You can set the background color instead of the foreground by prepending
+        ``on_``, as in ``on_blue``. There is also a ``bright`` version of each color:
+        for example, ``on_bright_blue``.
+        
+        There is also a numerical interface to colors, which takes an integer from
+        0-15::
+        
+            term.color(5) + 'Hello' + term.normal
+            term.on_color(3) + 'Hello' + term.normal
+        
+            term.color(5)('Hello')
+            term.on_color(3)('Hello')
+        
+        If some color is unsupported (for instance, if only the normal colors are
+        available, not the bright ones), trying to use it will, on most terminals, have
+        no effect: the foreground and background colors will stay as they were. You can
+        get fancy and do different things depending on the supported colors by checking
+        `number_of_colors`_.
+        
+        .. _`number_of_colors`: http://packages.python.org/blessings/#blessings.Terminal.number_of_colors
+        
+        Compound Formatting
+        -------------------
+        
+        If you want to do lots of crazy formatting all at once, you can just mash it
+        all together::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            print term.bold_underline_green_on_yellow + 'Woo' + term.normal
+        
+        Or you can use your newly coined attribute as a wrapper, which implicitly sets
+        everything back to normal afterward::
+        
+            print term.bold_underline_green_on_yellow('Woo')
+        
+        This compound notation comes in handy if you want to allow users to customize
+        the formatting of your app: just have them pass in a format specifier like
+        "bold_green" on the command line, and do a quick ``getattr(term,
+        that_option)('Your text')`` when you do your formatting.
+        
+        I'd be remiss if I didn't credit couleur_, where I probably got the idea for
+        all this mashing.
+        
+        .. _couleur: http://pypi.python.org/pypi/couleur
+        
+        Parametrized Capabilities
+        -------------------------
+        
+        Some capabilities take parameters. Rather than making you dig up ``tparm()``
+        all the time, we simply make such capabilities into callable strings. You can
+        pass the parameters right in::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            print term.move(10, 1)
+        
+        Here are some of interest:
+        
+        ``move``
+          Position the cursor elsewhere. Parameters are y coordinate, then x
+          coordinate.
+        ``move_x``
+          Move the cursor to the given column.
+        ``move_y``
+          Move the cursor to the given row.
+        
+        You can also reference any other string-returning capability listed on the
+        `terminfo man page`_ by its name under the "Cap-name" column.
+        
+        .. _`terminfo man page`: http://www.manpagez.com/man/5/terminfo/
+        
+        Height and Width
+        ----------------
+        
+        It's simple to get the height and width of the terminal, in characters::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            height = term.height
+            width = term.width
+        
+        These are newly updated each time you ask for them, so they're safe to use from
+        SIGWINCH handlers.
+        
+        Temporary Repositioning
+        -----------------------
+        
+        Sometimes you need to flit to a certain location, print something, and then
+        return: for example, when updating a progress bar at the bottom of the screen.
+        ``Terminal`` provides a context manager for doing this concisely::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            with term.location(0, term.height - 1):
+                print 'Here is the bottom.'
+            print 'This is back where I came from.'
+        
+        Parameters to ``location()`` are ``x`` and then ``y``, but you can also pass
+        just one of them, leaving the other alone. For example... ::
+        
+            with term.location(y=10):
+                print 'We changed just the row.'
+        
+        If you want to reposition permanently, see ``move``, in an example above.
+        
+        Pipe Savvy
+        ----------
+        
+        If your program isn't attached to a terminal, like if it's being piped to
+        another command or redirected to a file, all the capability attributes on
+        ``Terminal`` will return empty strings. You'll get a nice-looking file without
+        any formatting codes gumming up the works.
+        
+        If you want to override this--like if you anticipate your program being piped
+        through ``less -r``, which handles terminal escapes just fine--pass
+        ``force_styling=True`` to the ``Terminal`` constructor.
+        
+        In any case, there is an ``is_a_tty`` attribute on ``Terminal`` that lets you
+        see whether the attached stream seems to be a terminal. If it's false, you
+        might refrain from drawing progress bars and other frippery, since you're
+        apparently headed into a pipe::
+        
+            from blessings import Terminal
+        
+            term = Terminal()
+            if term.is_a_tty:
+                with term.location(0, term.height - 1):
+                    print 'Progress: [=======>   ]'
+            print term.bold('Important stuff')
+        
+        Shopping List
+        =============
+        
+        There are decades of legacy tied up in terminal interaction, so attention to
+        detail and behavior in edge cases make a difference. Here are some ways
+        Blessings has your back:
+        
+        * Uses the terminfo database so it works with any terminal type
+        * Provides up-to-the-moment terminal height and width, so you can respond to
+          terminal size changes (SIGWINCH signals). (Most other libraries query the
+          ``COLUMNS`` and ``LINES`` environment variables or the ``cols`` or ``lines``
+          terminal capabilities, which don't update promptly, if at all.)
+        * Avoids making a mess if the output gets piped to a non-terminal
+        * Works great with standard Python string templating
+        * Provides convenient access to all terminal capabilities, not just a sugared
+          few
+        * Outputs to any file-like object, not just stdout
+        * Keeps a minimum of internal state, so you can feel free to mix and match with
+          calls to curses or whatever other terminal libraries you like
+        
+        Blessings does not provide...
+        
+        * Native color support on the Windows command prompt. However, it should work
+          when used in concert with colorama_.
+        
+        .. _colorama: http://pypi.python.org/pypi/colorama/0.2.4

+        
+        Version History
+        ===============
+        
+        1.3
+          * Add ``number_of_colors``, which tells you how many colors the terminal
+            supports.
+          * Made ``color(n)`` and ``on_color(n)`` callable to wrap a string, like the
+            named colors can. Also, make them both fall back to the ``setf`` and
+            ``setb`` capabilities (like the named colors do) if the ANSI ``setaf`` and
+            ``setab`` aren't available.
+          * Allow ``color`` attr to act as an unparametrized string, not just a
+            callable.
+          * Make ``height`` and ``width`` examine any passed-in stream before falling
+            back to stdout. (This rarely if ever affects actual behavior; it's mostly
+            philosophical.)
+          * Make caching simpler and slightly more efficient.
+          * Get rid of a reference cycle between Terminals and FormattingStrings.
+          * Update docs to reflect that terminal addressing (as in ``location()``) is
+            0-based.
+        
+        1.2
+          * Added support for Python 3! We need 3.2.3 or greater, because the curses
+            library couldn't decide whether to accept strs or bytes before that
+            (http://bugs.python.org/issue10570).
+          * Everything that comes out of the library is now unicode. This lets us
+            support Python 3 without making a mess of the code, and Python 2 should
+            continue to work unless you were testing types (and badly). Please file a
+            bug if this causes trouble for you.
+          * Changed to the MIT License for better world domination.
+          * Added Sphinx docs.
+        
+        1.1
+          * Added nicely named attributes for colors.
+          * Introduced compound formatting.
+          * Added wrapper behavior for styling and colors.
+          * Let you force capabilities to be non-empty, even if the output stream is
+            not a terminal.
+          * Added the ``is_a_tty`` attribute for telling whether the output stream is a
+            terminal.
+          * Sugared the remaining interesting string capabilities.
+          * Let ``location()`` operate on just an x *or* y coordinate.
+        
+        1.0
+          * Extracted Blessings from nose-progressive, my `progress-bar-having,
+            traceback-shortcutting, rootin', tootin' testrunner`_. It provided the
+            tootin' functionality.
