Ubic is a toolkit for describing services on Linux in perl. It's been implemented in-house at Yandex as a better way to run daemons than writing ugly SysV-style /etc/init.d scripts, and i've put it on github and CPAN recently.
I also gave a lightning talk about it at YAPC::Russia::2010 in Kiev several days ago, it should explain most of its traits:
So... any feedback? :)
PS: Several Ubic::Service::* modules are not in public domain yet - i'll have to do some cleanup first, hopefully in next week or two.
