+"""A simple parser for configuration files in ini-style.
+
+The main difference to other simple ini-parsers is, that it does not
+write the whole structure into the file, but only the changed values.
+Thus it keeps comments and structuring of the file.

+@var DELIMITER: list of delimiters allowed
+@type DELIMITER: string[]
+
+@var COMMENT: comment marks allowed
+@type COMMENT: string[]
+
+@var TRUE: Regular expression for all TRUE values allowed.
+Currently supported are the values (case insensitive): true, 1, on, wahr, ja, yes.
+@var FALSE: Regular expression for all FALSE values allowed.
+Currently supported are the values (case insensitive): false, 0, off, falsch, nein, no,
+@var SECTION: Regular expression allowing the recognition of a section header.
+@var EXPRESSION: Regular expression defining a normal option-value pair.
