[Catalyst] YAML Config

[Oleg Pronin]

There is a var dir.
There are log dir, pid dir and data dir under var dir.
And a somelog.log under log dir.

Do you suggest to write
var_dir: __path_to(var)__
log_dir: __path_to(var/log)__
somelog: __path_to(var/log/somelog.log)__
pid_dir: __path_to(var/pid)__
data_dir: __path_to(var/data)__

?

Too many copy-pasting. And too many to change when var_dir changes.
