4 #
5 # Vlad is one of the delivery method options available out of the
6 # box with Sprinkle. If you have the vlad the deployer gem install, you
7 # may use this delivery. The only configuration option available, and
8 # which is mandatory to include is +script+. An example:
9 #
10 # deployment do
11 # delivery :vlad do
12 # script 'deploy'
13 # end
14 # end
15 #
16 # script is given a list of files which capistrano will include and load.
17 # These recipes are mainly to set variables such as :user, :password, and to
18 # set the app domain which will be sprinkled.
