New Revision: 8211
Added:
trunk/WIP/broken_helpers/mbusctl.py
- copied unchanged from r8200, /trunk/ui/src/helpers/mbusctl.py
Removed:
trunk/ui/src/helpers/
Modified:
trunk/ui/bin/freevo
Log:
Move main helper script to freevo bin script. There are no helpers anymore,
freevo script doing extra stuff should go into apps. This is a much cleaner
design. Special stuff like starting in background is planned.
