"""
Package implementing the preferences interface.

The preferences interface consists of a class, which defines the default
values for all configuration items and stores the actual values. These
values are read and written to the eric5 preferences file by module
functions. The data is stored in a file in a subdirectory of the users home
directory. The individual configuration data is accessed by accessor functions
defined on the module level. The module is simply imported wherever it is
needed with the statement 'import Preferences'. Do not use
'from Preferences import *' to import it.
