Configuration file parser
=========================

Configuration file parser.  This module was written by Ken Manheimer

This module defines the class `ConfigParser'.  The `ConfigParser' class
implements a basic configuration file parser language which provides a
structure similar to what you would find on Microsoft Windows INI
files.  You can use this to write Python programs which can be
customized by end users easily.

The configuration file consists of sections, lead 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 upon initialization and retrieval.  Lines beginning with `#' or
`;' are ignored and may be used to provide comments.

For example:

     foodir: %(dir)s/whatever
     dir=frob

would resolve the `%(dir)s' to the value of `dir' (`frob' in this
case).  All reference expansions are done on demand.

Default values can be specified by passing them into the `ConfigParser'
constructor as a dictionary.  Additional defaults may be passed into
the `get()' method which will override all others.

`ConfigParser([defaults])'
     Return a new instance of the `ConfigParser' class.  When DEFAULTS
     is given, it is initialized into the dictionary of intrinsic
     defaults.  The keys must be strings, and the values must be
     appropriate for the `%()s' string interpolation.  Note that
     __NAME__ is an intrinsic default; its value is the section name,
     and will override any value provided in DEFAULTS.

`NoSectionError'
     Exception raised when a specified section is not found.

`DuplicateSectionError'
     Exception raised when multiple sections with the same name are
     found, or if `add_section()' is called with the name of a section
     that is already present.

`NoOptionError'
     Exception raised when a specified option is not found in the
     specified section.

`InterpolationError'
     Exception raised when problems occur performing string
     interpolation.

`InterpolationDepthError'
     Exception raised when string interpolation cannot be completed
     because the number of iterations exceeds `MAX_INTERPOLATION_DEPTH'.

`MissingSectionHeaderError'
     Exception raised when attempting to parse a file which has no
     section headers.

`ParsingError'
     Exception raised when errors occur attempting to parse a file.

`MAX_INTERPOLATION_DEPTH'
     The maximum depth for recursive interpolation for `get()' when the
     RAW parameter is false.  Setting this does not change the allowed
     recursion depth.

     which can be used as an alternate format for application
     configuration files.
