 """
 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.
