Chad,
In that case, you do best to set a variable, you might want to check the
wiki (http://capify.org) for set and see how else it can be used, fetch
/etc?
I forget the syntax off hand, but consider this:
task :get_keys do
set :key, lambda { Capistrano::UI.ask("Please enter a key:") } unless
fetch(:key)
end
before :get_keys
..... maybe something like that would work for you?
