+:mod:`stringprep` --- Internet String Preparation
+=================================================
+
+.. module:: stringprep
+   :synopsis: String preparation, as per RFC 3453
+   :deprecated:
+.. moduleauthor:: Martin v. Löwis <martin@v.loewis.de>
+.. sectionauthor:: Martin v. Löwis <martin@v.loewis.de>
+
+
+.. versionadded:: 2.3
+
+When identifying things (such as host names) in the internet, it is often
+necessary to compare such identifications for "equality". Exactly how this
+comparison is executed may depend on the application domain, e.g. whether it
+should be case-insensitive or not. It may be also necessary to restrict the
+possible identifications, to allow only identifications consisting of
+"printable" characters.
+
+:rfc:`3454` defines a procedure for "preparing" Unicode strings in internet
+protocols. Before passing strings onto the wire, they are processed with the
+preparation procedure, after which they have a certain normalized form. The RFC
+defines a set of tables, which can be combined into profiles. Each profile must
+define which tables it uses, and what other optional parts of the ``stringprep``
+procedure are part of the profile. One example of a ``stringprep`` profile is
+``nameprep``, which is used for internationalized domain names.
+
+The module :mod:`stringprep` only exposes the tables from RFC 3454. As these
+tables would be very large to represent them as dictionaries or lists, the
+module uses the Unicode character database internally. The module source code
+itself was generated using the ``mkstringprep.py`` utility.
+
+As a result, these tables are exposed as functions, not as data structures.
+There are two kinds of tables in the RFC: sets and mappings. For a set,
+:mod:`stringprep` provides the "characteristic function", i.e. a function that
+returns true if the parameter is part of the set. For mappings, it provides the
+mapping function: given the key, it returns the associated value. Below is a
+list of all functions available in the module.
+
+
+.. function:: in_table_a1(code)
+
+   Determine whether *code* is in tableA.1 (Unassigned code points in Unicode 3.2).
+
+
+.. function:: in_table_b1(code)
+
+   Determine whether *code* is in tableB.1 (Commonly mapped to nothing).
+
+
+.. function:: map_table_b2(code)
+
+   Return the mapped value for *code* according to tableB.2 (Mapping for
+   case-folding used with NFKC).
+
+
+.. function:: map_table_b3(code)
+
+   Return the mapped value for *code* according to tableB.3 (Mapping for
+   case-folding used with no normalization).
+
+
+.. function:: in_table_c11(code)
+
+   Determine whether *code* is in tableC.1.1  (ASCII space characters).
+
+
+.. function:: in_table_c12(code)
+
+   Determine whether *code* is in tableC.1.2  (Non-ASCII space characters).
+
+
+.. function:: in_table_c11_c12(code)
+
+   Determine whether *code* is in tableC.1  (Space characters, union of C.1.1 and
+   C.1.2).
+
+
+.. function:: in_table_c21(code)
+
+   Determine whether *code* is in tableC.2.1  (ASCII control characters).
+
+
+.. function:: in_table_c22(code)
+
+   Determine whether *code* is in tableC.2.2  (Non-ASCII control characters).
+
+
+.. function:: in_table_c21_c22(code)
+
+   Determine whether *code* is in tableC.2  (Control characters, union of C.2.1 and
+   C.2.2).
+
+
+.. function:: in_table_c3(code)
+
+   Determine whether *code* is in tableC.3  (Private use).
+
+
+.. function:: in_table_c4(code)
+
+   Determine whether *code* is in tableC.4  (Non-character code points).
+
+
+.. function:: in_table_c5(code)
+
+   Determine whether *code* is in tableC.5  (Surrogate codes).
+
+
+.. function:: in_table_c6(code)
+
+   Determine whether *code* is in tableC.6  (Inappropriate for plain text).
+
+
+.. function:: in_table_c7(code)
+
+   Determine whether *code* is in tableC.7  (Inappropriate for canonical
+   representation).
+
+
+.. function:: in_table_c8(code)
+
+   Determine whether *code* is in tableC.8  (Change display properties or are
+   deprecated).
+
+
+.. function:: in_table_c9(code)
+
+   Determine whether *code* is in tableC.9  (Tagging characters).
+
+
+.. function:: in_table_d1(code)
+
+   Determine whether *code* is in tableD.1  (Characters with bidirectional property
+   "R" or "AL").
+
+
+.. function:: in_table_d2(code)
+
+   Determine whether *code* is in tableD.2  (Characters with bidirectional property
+   "L").
