Manage diffusions using schedules, to update, clean up or check diffusions.
|
|
|
|
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
|
|
schedules for the (given) month.
|
|
|
|
- "clean" will remove all diffusions that are still unconfirmed and have been
|
|
planified before the (given) month.
|
|
|
|
- "check" will remove all diffusions that are unconfirmed and have been planified
|
|
from the (given) month and later.
