urgencies into consideration. If empty (or not updated), the policy

|
will simply use the default urgency (see the "Config" section below)
|
|
- In Debian, these values are taken from the .changes file, but that is
|
|
not a requirement for Britney.
|
|
* ${STATE_DIR}/age-policy-dates: File containing the age of all source
|
|
packages.
|
|
- The policy will automatically update this file.
|
|
Config:
|
|
* DEFAULT_URGENCY: Name of the urgency used for packages without an urgency

(or for unknown urgencies). Will also be used to set the "minimum"
|
|
aging requirements for packages not in the target suite.
|

* MINDAYS_<URGENCY>: The age-requirements in days for packages with the
