Title: if ack is not installed finish script

if the ack program is not installed, finish the script of plugin,

if ack is not installed, why use the plugin ?

I use ack.vim as a submodule of a git repo with dotfiles and vim configurations files, and when I use the configurations files in windows (with cygwin), I don't have installed ack program.
