+"""Configuration file parser.
+
+A setup file consists of sections, lead by a "[section]" header,
+and followed by "name: value" entries, with continuations and such in
+the style of rfc822.
+
+The option values can contain format strings which refer to other
+values in the same section, or values in a special [DEFAULT] section.
+For example:
+
+    something: %(dir)s/whatever
+
+would resolve the "%(dir)s" to the value of dir.  All reference
+expansions are done late, on demand.
+
+Intrinsic defaults can be specified by passing them into the
+ConfigParser constructor as a dictionary.
+
+class:
+
+ConfigParser -- responsible for for parsing a list of
+                configuration files, and managing the parsed database.
+
+    methods:
+
+    __init__(defaults=None) -- create the parser and specify a

+                               keys must be strings, the values must
+                               be appropriate for %()s string
+                               interpolation.  Note that `name' is
+                               always an intrinsic default; it's value
+                               is the section's name.
