The configuration file consists of sections, led by a ``[section]`` header and
followed by ``name: value`` entries, with continuations in the style of
:rfc:`822`; ``name=value`` is also accepted. Note that leading whitespace is
removed from values. The optional values can contain format strings which refer
to other values in the same section, or values in a special ``DEFAULT`` section.
Additional defaults can be provided on initialization and retrieval. Lines
beginning with ``'#'`` or ``';'`` are ignored and may be used to provide
comments.
:rfc:`822` (see section 3.1.1, "LONG HEADER FIELDS"); ``name=value`` is also
accepted. Note that leading whitespace is removed from values. The optional
values can contain format strings which refer to other values in the same
section, or values in a special ``DEFAULT`` section. Additional defaults can be
provided on initialization and retrieval. Lines beginning with ``'#'`` or
``';'`` are ignored and may be used to provide comments.
For example::
[My Section]
foodir: %(dir)s/whatever
dir=frob
long: this value continues
in the next line
would resolve the ``%(dir)s`` to the value of ``dir`` (``frob`` in this case).
All reference expansions are done on demand.
