        ## Overview
        
        Pretty Traceback groups together what belongs together, adds coloring and alignment. All of this makes it easier for you to see patterns and filter out the signal from the noise. This tabular format is best viewed in a wide terminal.
        
        In other words, get this 😍

        If your terminal is wide enough, the long paths preserved.

        </div>
        
        
        ## Usage
        
        Add the following to your `__main__.py` or the equivalent module which is your entry point.
        
        ```python
        try:
            import pretty_traceback
            pretty_traceback.install()
        except ImportError:
            pass    # no need to fail because of missing dev dependency
        ```
        
        Please do not add this code e.g. to your `__init__.py` or any other module that your users may import. They may not want you to mess with how their tracebacks are printed.
        
        If you do feel the overwhelming desire to import the `pretty_traceback` in code that others might import, consider using the `envvar` argument, which will cause the install function to effectively be a noop unless you set `ENABLE_PRETTY_TRACEBACK=1`.
        
        ```python
        try:
            import pretty_traceback
            pretty_traceback.install(envvar='ENABLE_PRETTY_TRACEBACK')
        except ImportError:
            pass    # no need to fail because of missing dev dependency
        ```
        
        Note, that the hook is only installed if the existing hook is the default. Any existing hooks that were installed before the call of `pretty_traceback.install` will be left in place.
        
        
        ## LoggingFormatter
        
        A `logging.Formatter` subclass is also available (e.g. for integration with `flask`).
        
        ```python
        import os
        from flask.logging import default_handler
        
        try:
            if os.getenv('FLASK_DEBUG') == "1":
                import pretty_traceback
                default_handler.setFormatter(pretty_traceback.LoggingFormatter())
        except ImportError:
            pass    # no need to fail because of missing dev dependency
        ```
