| """Provides access to stored IDLE configuration information.
 | |
| 
 | |
| Refer to the comments at the beginning of config-main.def for a description of
 | |
| the available configuration files and the design implemented to update user
 | |
| configuration information.  In particular, user configuration choices which
 | |
| duplicate the defaults will be removed from the user's configuration files,
 | |
| and if a file becomes empty, it will be deleted.
 | |
| 
 | |
| The contents of the user files may be altered using the Options/Configure IDLE
 | |
| menu to access the configuration GUI (configDialog.py), or manually.
 | |
| 
 | |
| Throughout this module there is an emphasis on returning useable defaults
 | |
| when a problem occurs in returning a requested configuration value back to
 | |
| idle. This is to allow IDLE to continue to function in spite of errors in
 | |
| the retrieval of config information. When a default is returned instead of
 | |
| a requested config value, a message is printed to stderr to aid in
 | |
| configuration problem notification and resolution.
