+:mod:`errno` --- Standard errno system symbols
+==============================================
+
+.. module:: errno
+ :synopsis: Standard errno system symbols.
+
+
+This module makes available standard ``errno`` system symbols. The value of each
+symbol is the corresponding integer value. The names and descriptions are
+borrowed from :file:`linux/include/errno.h`, which should be pretty
+all-inclusive.
+
+
+.. data:: errorcode
+
+ Dictionary providing a mapping from the errno value to the string name in the
+ underlying system. For instance, ``errno.errorcode[errno.EPERM]`` maps to
+ ``'EPERM'``.
+
+To translate a numeric error code to an error message, use :func:`os.strerror`.
+
+Of the following list, symbols that are not used on the current platform are not
+defined by the module. The specific list of defined symbols is available as
+``errno.errorcode.keys()``. Symbols available can include:
+
