Description: 🚶 stroll: a better os.path.walk 🚶
        -------------------------------------
        
        ``stroll`` is a drop-in substitute for ``os.path.walk()`` with more features:
        
        * Unix-style globs or "star notation" like \*.py
        
        * Walks over multiple roots
        
        * Calls expanduser to handle paths like ``~/foo.txt``
        
        * Yields ``pathlib.Path()`` instead of ``str``
        
        * Yields full absolute paths by default
        
        * Can exclude or include files flexibly by pattern or function
        
        * Raises ``FileNotFoundError`` if a root directory doesn't exist, instead
          of silently doing nothing like ``os.walk`` does
        
        * Excludes dotfiles by default
        
        * Includes two functions for ignoring generated files in a Python project:
        
          * The Python build, test and release cycle tend to leave generated files in
            places like ``build/`` or ``__pycache__/``, and usually you want to ignore
            these
        
          * ``stroll.python_source()`` iterates over Python source files
        
          * ``stroll.python()`` iterates over all source files in a Python project
        
          * The files and directories that are ignored are:
              * files or directories that start with a ``.``
              * ``.egg-info/`` and ``__pycache__/``
              * ``build/``, ``dist/`` and ``htmlcov/`` at the top level only

        Directory walker that improves on ``os.walk()``.
        
        For each directory in ``roots``, walk through each file in each
        subdirectory and yield a Path to that file.  Ignores dotfiles by default.
        
        EXAMPLE
        
        .. code-block:: python
        
            import stroll
        
            for f in stroll('~/foo:~/bar'):
                if f.suffix == '.txt':
                    print(f)
        
            for f in stroll.python_source('/code/project'):
                assert f.suffix == '.py'
        
        ARGUMENTS
          roots
            Either a list or tuple of strings, or a single string that is split
            using ``separator`` (defaults to ``,``, the comma).
        
          topdown (argument to ``os.walk``)
            If optional arg ``topdown`` is true or not specified, the ``Path`` to a
            directory is generated before any of its subdirectories - directories
            are generated top-down.
        
            If ``topdown`` is false, the Path to a directory is generated after all
            of its subdirectories - directories are generated bottom up.
        
          onerror (argument to ``os.walk``)
            By default errors from the ``os.scandir()`` call are ignored.  If
            optional arg ``onerror`` is specified, it should be a function; it
            will be called with one argument, an OSError instance.  It can
            report the error to continue with the walk, or raise the exception
            to abort the walk.  Note that the filename is available as the
            filename attribute of the exception object.
        
          followlinks (argument to ``os.walk``)
            By default, ``os.walk()`` does not follow symbolic links to
            subdirectories on systems that support them.  In order to get this
            functionality, set the optional argument ``followlinks`` to true.
        
            Caution:  if you pass a relative pathname for top, don't change the
            current working directory between resumptions of walk.  ``os.walk()``
            never changes the current directory, and assumes that the client
            doesn't either.
        
          include
            A list of patterns that files must match.
        
            Patterns can either be a Unix-style match string,
            or a Python callable which returns ``True`` if the file matches
        
          exclude
            A list of patterns that files cannot match (and will skip).
        
            Patterns can either be a Unix-style match string,
            or a Python callable which returns ``True`` if the file matches.
        
          directories
            If true, both files and directories are yielded.
            If false, the default, only files are yielded
        
          relative
            If true, file paths are relative to the root they were found in.
            If false, the default, absolute paths are generated.
        
          with_root
            If true, pairs looking like (root, filepath) are generated.
            If ``False``, just file paths are generated.
            If ``None``, the default, pairs are generated only if there is more than
            one root *and* relative paths are selected.
        
          sort
            If true, files or subdirectories are generated in sorted order.
            If false, the default, files or subdirectories are generated in
            whatever order the operating system gives them, which might be
            sorted anyway
        
          suffix
             If ``None``, the default, there is no suffix matching.  Note that
             ``include`` and ``exclude`` might match suffixes independently.
        
          ignore_missing_roots
            If true, root directories that do not exist are silently skipped.
            If false, the default, all roots are checked for existence before
            any files are generated.
