Manage diffusions using schedules, to update, clean up or check diffusions.
|
||||
A diffusion generated using this utility is considered has type "unconfirmed",
|
||||
and is not considered as ready for diffusion; To do so, users must confirm the
|
||||
diffusion case by changing it's type to "default".
|
||||
|
||||
A generated diffusion can be unconfirmed, that means that the user must confirm
|
||||
it by changing its type to "normal". The behaviour is controlled using
|
||||
--approval.
|
||||
|
||||
|
||||
Different actions are available:
|
||||
- "update" is the process that is used to generated them using programs
