�S ) a� A helper function that intelligently wraps text. By default, it
assumes that it operates on a single paragraph of text but if the
`preserve_paragraphs` parameter is provided it will intelligently
handle paragraphs (defined by two empty lines).
If paragraphs are handled, a paragraph can be prefixed with an empty
line containing the ``\b`` character (``\x08``) to indicate that
no rewrapping should happen in that block.
:param text: the text that should be rewrapped.
:param width: the maximum width for the text.
:param initial_indent: the initial indent that should be placed on the
first line as a string.
:param subsequent_indent: the indent string that should be placed on
each consecutive line.
:param preserve_paragraphs: if this flag is set then the wrapping will
intelligently handle paragraphs.

HelpFormattera� This class helps with formatting text-based help pages. It's
usually just needed for very special internal cases, but it's also
exposed so that developers can write their own fancy outputs.
At present, it always writes into memory.
:param indent_increment: the additional increment for each level.
:param width: the width for the text. This defaults to the terminal
width clamped to a maximum of 78.

second column.
