This is supposed to be used in abuild only to make it possible to exit with error early, before package is built, in case the signing key is missing.

No private key found. Use 'abuild-keygen' to generate the keys.
|

Then you can either:
|
|
* set the PACKAGER_PRIVKEY in $ABUILD_USERCONF
|
|
('abuild-keygen -a' does this for you)
|
|
* set the PACKAGER_PRIVKEY in $ABUILD_CONF
|
|
* specify the key with the -k option to $program
