Attempts to find the task at the given fully-qualified path, and alias it. If arguments don't have correct task names, an ArgumentError wil be raised. If no such task exists, a Capistrano::NoSuchTaskError will be raised.

Usage:

alias_task :original_deploy, :deploy
# File lib/capistrano/configuration/alias_task.rb, line 13
def alias_task(new_name, old_name)
  if !new_name.respond_to?(:to_sym) or !old_name.respond_to?(:to_sym)
    raise ArgumentError, "expected a valid task name"
  end

  original_task = find_task(old_name) or raise NoSuchTaskError, "the task `#{old_name}' does not exist"
  task = original_task.dup # Dup. task to avoid modify original task
  task.name = new_name

  define_task(task)
end
