| 3 This module is based on a rox module (LGPL): | |
| 4 | |
| 5 http://cvs.sourceforge.net/viewcvs.py/rox/ROX-Lib2/python/rox/basedir.py?rev=1.9&view=log | |
| 6 | |
| 7 The freedesktop.org Base Directory specification provides a way for | |
| 8 applications to locate shared data and configuration: | |

| 10 http://standards.freedesktop.org/basedir-spec/ | |
| 11 | |
| 12 (based on version 0.6) | |
| 13 | |
| 14 This module can be used to load and save from and to these directories. | |
| 15 | |
| 16 Typical usage: | |
| 17 | |
| 18 from rox import basedir | |
| 19 | |
| 20 for dir in basedir.load_config_paths('mydomain.org', 'MyProg', 'Options'): | |
| 21 print "Load settings from", dir | |
| 22 | |
| 23 dir = basedir.save_config_path('mydomain.org', 'MyProg') | |
| 24 print >>file(os.path.join(dir, 'Options'), 'w'), "foo=2" | |
| 25 | |
| 26 Note: see the rox.Options module for a higher-level API for managing options. | |
