[Koha-devel] Restart plack when needed

[Paul Poulain]

wow! impressive !

Is the option --reload shipped with packages ? Because if I'm not wrong, 
it's "useless" in a production environment: you know when you update 
your Koha and you can restart plack manually or trough the packages 
post-update scripts, isn't it ?
